“His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child.“
Kaitlin “Kati” Hill told ABC News those words after her three-year-old son, Colton, suffered a broken femur at a trampoline park. He spent the following months in a body cast. Like so many families in Mustang Ridge, Kati trusted the facility’s marketing. She believed that “Toddler Time” meant the environment was engineered for her child’s safety. She later admitted the truth that haunts thousands of parents: “We had no idea. We would have never put our baby boy on a trampoline if we would have known.“
What happened to Colton wasn’t a “freak accident.” It wasn’t “bad luck.” It was the predictable output of a business model that prioritizes throughput and profit margins over the orthopedic integrity of a child’s developing skeleton. In Mustang Ridge, where families travel north on SH 130 or I-35 to reach the massive adventure parks in Austin or San Marcos, the risk is real, constant, and catastrophic.
We are The Manginello Law Firm—Attorney911. Our founder, Ralph Manginello, has spent 25+ years making Fortune 500 corporations and institutional defendants pay for their failures. We’ve gone toe-to-toe with BP after the Texas City refinery explosion and litigated against giants like Walmart and Amazon. We’re currently litigating a $10 million lawsuit involving rhabdomyolysis and acute kidney failure—the exact same muscle and organ breakdown we see in children who are pushed too hard in hot, indoor jump facilities.
Our associate attorney, Lupe Peña, provides our clients with an advantage few firms in the country can claim: he used to sit on the other side of the table. He spent years defending insurance companies and recreational businesses against the very same injury claims we now bring. He knows exactly how these parks try to hide behind a piece of paper you signed at a kiosk, and he knows exactly how to tear those waivers apart.
If your child was injured in Mustang Ridge or at any park serving the Caldwell County area, you need to understand one thing clearly: The waiver you signed is not a wall. It is noise. We have memorized the standards they violate—ASTM F2970 for commercial parks and ASTM F381 for backyard equipment. We know the physics of the double-bounce, the biology of the Salter-Harris fracture, and the corporate archeology required to find the money hidden behind layers of shell companies.
The clock is running. Mustang Ridge families deserve more than an attorney who “handles” personal injury. You need a system that wins. Call us at 1-888-ATTY-911. Hablamos Español. Our spoliation letter demanding the preservation of surveillance video and incident reports goes out within 24 hours of your call.
Why a Trampoline Injury in Mustang Ridge Is Never an “Accident”
In personal injury law, we distinguish between unavoidable mishaps and systemic failures. A trampoline injury is a business decision. When a park in the Mustang Ridge corridor decides to staff a Saturday afternoon rush with a monitor-to-jumper ratio of 1:60 instead of the industry-recommended 1:32, they are making a decision to accept a certain number of broken legs to save on labor costs.
When a manufacturer like Jumpking or Skywalker sells a backyard trampoline to a family in Mustang Ridge despite the American Academy of Pediatrics (AAP) warning against home use since 1999, they are making a decision to ignore medical consensus for the sake of quarterly revenue.
We don’t accept the industry’s spin. We look at the “Seven Rungs of Foreseeability” that every catastrophic case in Mustang Ridge climbs:
- Medical Consensus: The AAP has been shouting the warning for 25+ years.
- Industry Standards: ASTM F2970 is the manual the industry wrote for itself to create a safety floor. They frequently fall through their own floor.
- CPSC Tracking: The Consumer Product Safety Commission has tracked hundreds of thousands of annual ER visits for decades.
- Chain-Wide Patterns: Franchisors like Sky Zone, Inc. and Unleashed Brands (Urban Air) have internal incident logs that prove they know which attractions maim children.
- Audit Reports: Internal audits at local parks often document the same violations (understaffing, old foam) months before a catastrophic injury occurs.
- Prior Similar Incidents: We subpoena the chain-wide history. If a Sky Rider zipline strangled a child in Georgia, the park in Texas is on notice.
- Financial Decisions: Identifying where private equity sponsors like Palladium Equity or Seidler Equity prioritized margin over maintenance.
When we build a case for a Mustang Ridge family, we aren’t just looking at the moment the bone snapped. We are looking at the months of corporate decisions that made that snap inevitable.
The Signature Mechanism: The Double-Bounce and the 14x Risk
One of the most common calls we get from Mustang Ridge parents involves a collision or a “bad landing” when another jumper was nearby. This is known legally and scientifically as the Double-Bounce.
The physics are brutal. Imagine a 200-pound adult jumping on an interconnected trampoline bed in a facility near Mustang Ridge. As the adult lands, the bed stores an enormous amount of elastic potential energy. If a 50-pound child is pushing off that same bed at that exact micro-second, that stored energy is transferred into the child. The child isn’t just jumping; they are being launched by a catapult.
The energy transfer multiples the child’s launch force by up to 4x. The child becomes an unguided projectile. On descent, their legs—specifically their tibias and femurs—cannot absorb the kinetic energy.
According to peer-reviewed research by Nysted & Drogset (British Journal of Sports Medicine), when a smaller child and a larger jumper share a trampoline, the smaller child is approximately 14 times more likely to be injured.
ASTM F2970 requires parks to operationalize weight-class and age-group separation. When a monitor at a park near Mustang Ridge lets a teenager into a toddler zone, or lets a father “help” his son jump, they are violating the standard of care. That violation is negligence. If they did it knowingly during a peak crowd to avoid conflict, it is gross negligence.
We recovered an $11.485 million verdict in Harris County against Cosmic Jump because we proved gross negligence despite a signed waiver. We apply that same tenacity to every double-bounce case we take in Mustang Ridge.
Foam Pits: The Illusion of Safety in the Mustang Ridge Corridor
Foam pits are the single most litigated attraction in the industry. They look soft, inviting, and safe for Mustang Ridge families. In reality, they are responsible for some of the most catastrophic outcomes we handle: permanent paralysis and cervical spinal cord injuries.
The foam blocks are made of open-cell polyurethane. Over time, they compress, tear, and lose their ability to decelerate a body. ASTM F2970 requires specific depths and rotation schedules, but many parks near Mustang Ridge fail to maintain them.
Head-First Entry and the SCIWORA Phenomenon
When a child dives into a foam pit and contact the hard floor beneath, the axial load can cause a cervical fracture. In children, we frequently see SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). A child in Mustang Ridge might come out of the pit with a “normal” X-ray or CT scan at the ER, but their spinal cord is suffering ischemic damage. Hours later, the paralysis sets in.
The Aspiration Hazard
Because foam blocks absorb sweat, sweat, and vomit, they are massive bacterial reservoirs. If a child lands head-first and begins to struggle, they can inhale foam dust or fluids. This is why we address the Infection and Sanitation Vertical (Section E.16) that most other Mustang Ridge lawyers ignore. MRSA and Group A Strep survive in these pits for weeks.
The industry knows the danger. That is why Sky Zone, Urban Air, and DEFY have been largely replacing foam pits with pressurized airbags since 2018. The industry’s move away from foam pits is a silent admission that they are unsafe. If your child was hurt in an old-style foam pit in a park near Mustang Ridge, we will use that industry-wide shift to prove the park chose a dangerous design to save on upgrade costs.
Mustang Ridge Parents: Understanding Your Rights Under Texas Law
Texas is a complex jurisdiction for injury victims. The insurance companies have a well-funded lobby in Austin, and they have pushed for laws that make it harder to sue. But catastrophic cases—those involving life-altering injuries—are governed by specific Texas doctrines that we have spent 25 years mastering.
The Munoz Rule: Parental Waivers Are Void for Children
In 1993, the case of Munoz v. II Jaz, Inc. established the rule we rely on for almost every pediatric case we handle in Mustang Ridge. The court held that a parent cannot sign away a minor child’s right to sue for personal injuries.
This means that even if you signed the iPad waiver at the park, your child’s individual legal claim remains intact. The park will try to tell you otherwise. The insurance adjuster will tell you the case is closed. They are wrong.
The Dresser “Fair Notice” Doctrine
For the parent’s own claim (or adult victims in Mustang Ridge), we look at the 1993 Texas Supreme Court decision in Dresser Industries v. Page Petroleum. Texas law says a waiver is only enforceable if it meets two tests:
- The Express Negligence Doctrine: It must specifically use the word “negligence.”
- Conspicuousness: The text must be bold, all-caps, or otherwise set apart.
Most “clickwrap” waivers on iPads at parks serving Mustang Ridge are procedurally unconscionable and fail the conspicuousness test. We know how to challenge them in court.
Gross Negligence and the Cosmic Jump $11.485M Verdict
No waiver in Texas can release a claim for gross negligence. Under the Moriel standard, if a park in the Mustang Ridge area was subjectively aware of an extreme risk and showed conscious indifference, the waiver is irrelevant.
In Harris County, a 16-year-old fell through a torn trampoline slide onto concrete. The park knew the tear was there. They didn’t fix it. The jury returned an $11.485 million verdict, including $6 million in punitive damages. That is the kind of accountability we fight for in Mustang Ridge.
The 2025 Jurisdictional Split
The law is moving quickly. In May 2025, the Texas Supreme Court issued its ruling in Cerna v. Pearland Urban Air. While this was a pro-defendant win on a technical “delegation clause,” it does not end the case. It moves the fight into arbitration. Our firm has experience winning $15 million+ awards in arbitration. We don’t fear the forum; we master the evidence.
The Evidence Clock: Why the Next 7 Days Are Critical for Mustang Ridge Families
In Mustang Ridge, the legal deadline (statute of limitations) to file a lawsuit is generally two years. But the evidence deadline is usually less than 30 days.
Trampoline parks are high-speed environments. They generate massive amounts of digital data, and they are designed to overwrite it quickly.
- Surveillance Video: Most park DVR systems in the Austin-San Antonio corridor are set to overwrite in 7 to 14 days. If we don’t send a spoliation letter immediately, the video of your child’s injury will be gone forever.
- Incident Reports: We’ve seen cases where the original incident report was “revised” 48 hours later to blame the parent or child. Our forensic discovery protocols pull the metadata to show when and who changed the document.
- Kiosk Logs: Waiver version histories and audit trails can be purged from the database in as little as 72 hours.
- Witness Turnover: The 17-year-old “court monitor” who saw your child get double-bounced will likely quit or transfer within 3 to 6 months. We have an Ex-Employee Outreach Protocol (G.16) to find them before their memory fades or the park puts a lawyer in front of them.
When we are retained by a Mustang Ridge family, our paralegal team immediately deploys our Operational Scaffolds. We file state open-records requests with the Texas Department of Insurance (TDI) to get the inspection history of the park’s Class B inflatables. We pull the FDD Item 3 disclosures to see how many times that franchisor has been sued for the same injury.
Medical Specificity: Beyond “Broken Bones”
An insurance adjuster in Mustang Ridge sees “broken leg” and thinks of a standard payout. We see a Salter-Harris Type III fracture of the distal tibial physis and we see a Pediatric Life-Care Plan.
Children’s bones contain growth plates (physes). Because these are cartilage, they are the weakest part of the skeleton. A fracture through a growth plate at age 9 in Mustang Ridge can lead to:
- Limb-Length Discrepancy: One leg growing longer than the other.
- Angular Deformity: The bone growing crooked.
- Correction Surgery: The need for osteotomies or epiphysiodesis years after the initial injury.
We work with pediatric orthopedic surgeons and life-care planners to forecast these costs over the next 50 years of your child’s life. We also understand the Rhabdomyolysis Bridge. If your child has dark, “cola-colored” urine or listlessness 24 hours after a hot Saturday afternoon jump session near Mustang Ridge, go to an ER now. Their muscles are breaking down, and their kidneys are at risk. We literately wrote the book on Texas rhabdo litigation with our $10M UH case.
Why Mustang Ridge Families Choose Attorney911
We represent families. We represent children. We represent the parent who is currently sitting in a pediatric trauma ward like Dell Children’s in Austin, wondering how they are going to pay for the three surgeries their son just had.
As our client Chad Harris said, “You are NOT just some client… You are FAMILY to them.“
We take on the conglomerates behind Sky Zone, Urban Air, and Altitude because we’ve spent our careers fighting bigger enemies. When an insurer tells us “the policy limit is only $1 million,” we find the umbrella. We find the franchisor’s additional-insured coverage. We find the manufacturer’s product-liability tower.
We advance every cost. Our Mustang Ridge clients pay nothing upfront. We pay for the biomechanical engineer who will model the energy transfer of the bounce. We pay for the digital forensic expert who will image the park’s DVR hard drive. We pay for the vocational rehabilitation expert who will calculate your child’s lost future earnings.
Frequently Asked Questions for Mustang Ridge Families
Can I sue if I signed an iPad waiver at an Austin or San Antonio park?
Yes. In Texas, a parent cannot waive a minor’s negligence claim per Munoz v. II Jaz. Furthermore, no waiver covers gross negligence. We attack waivers on five separate vectors, including the Delfingen Doctrine if your primary language is Spanish and the waiver was in English.
How much is my child’s trampoline injury case worth?
Every case is unique, but national and Texas data provide anchors. A serious pediatric femur fracture or growth-plate injury can reach settlements in the $500,000 to $2.5 million range. Traumatic brain injuries and spinal cord injuries frequently produce nuclear verdicts and settlements exceeding $10 million.
Who is liable for a backyard trampoline injury in Mustang Ridge?
Often, several parties. We look at the Homeowner (premises liability/attractive nuisance), the Manufacturer (Jumpking, Skywalker, ACON, etc. for product defects), and the Retailer (Walmart, Amazon, Costco) who sold a product they knew to be dangerous.
The park’s insurance company offered us $3,000 “Med-Pay.” Should we take it?
No. This is the Med-Pay Trojan Horse. These checks often come with a release on the back. Depositing it can end your entire claim. Always have an attorney review an offer before you sign or deposit anything.
What are the “Walk-Out Red Flags”?
If you walk into a park near Mustang Ridge and see a monitor on their phone, torn padding on any court, or large teenagers jumping in a toddler zone—leave immediately. Your child’s life is worth more than a $20 ticket.

Understanding the Corporate Stack: Who Really Owns the Park?
When your child is hurt at an Urban Air or a Sky Zone, the park’s lawyer will try to tell you it was an “isolated incident” at a “small local business.” We know better.
Sky Zone, Inc. was renamed from CircusTrix in 2023. It is backed by Palladium Equity Partners, a multi-billion dollar private equity firm. Urban Air’s parent, Unleashed Brands, was acquired by Seidler Equity Partners in 2023. These aren’t mom-and-pop shops. These are massive corporate towers designed to route profit to investors while leaving local managers understaffed and undertrained.
We pierce those shields. We identify the operator LLC, the franchisee holding group, the franchisor, the brand parent, and the private equity sponsor. The money is upstream. We go upstream.
