On any given Saturday afternoon, families from the Town of Copper Canyon travel just a few miles south or east to the massive entertainment hubs in Southlake, Denton, or Frisco. You might be at the Urban Air in Southlake—the flagship location where the entire franchise began—or perhaps the Altitude in Fort Worth Keller. You signed the waiver at the kiosk because the line was long and your children were vibrating with excitement. You handed them their grip socks, told them to have fun, and found a seat at the observation rail.
Then, the scream happens. As Kaitlin “Kati” Hill told ABC News after her son Colton’s femur was shattered at a park, it is “the worst scream that you could ever have heard from a child.”
In that split second, your life in the Town of Copper Canyon changes. The park manager approaches not with a medical kit or an ambulance on speed dial, but with a clipboard and a “guest error” form. You are told the injury was an “inherent risk.” You are reminded that you signed a waiver. At the emergency room at Cook Children’s or a trauma bay in Denton, the surgeon explains that your child has a Salter-Harris Type III fracture—a growth plate injury that may not stop causing problems until they reach adulthood.
We are Attorney911, The Manginello Law Firm. We don’t accept the park’s “inherent risk” excuse, and we certainly don’t accept their waiver as a wall. Our founder, Ralph Manginello, has spent over 25 years making corporate defendants pay for catastrophic injuries. Our team includes a former insurance defense attorney, Lupe Peña, who used to write the very waiver language these parks rely on. He knows their playbook because he helped create it—and now he uses that knowledge to dismantle it.
If your family is dealing with a trampoline injury in the Town of Copper Canyon, you aren’t just looking for an attorney. You’re looking for the firm that knows the industry better than the operators themselves.
The Systemic Architecture of Trampoline Injuries in Denton County
A trampoline injury in the Town of Copper Canyon is never just an accident. It is the predictable output of a business model that prioritizes throughput and margin over pediatric safety. While you see a place for your kids to burn off energy, the parent conglomerates behind these parks—companies like Sky Zone, Inc. (backed by Palladium Equity Partners) and Unleashed Brands (the Seidler Equity-owned parent of Urban Air)—see a high-volume revenue engine.
The math they use is brutal. To reach their sales targets, they understaff courts, ignore age-separation requirements, and defer maintenance on foam pits and airbags. They operate under a voluntary standard, ASTM F2970, which the trampoline park industry drafted for itself. When they violate it, they aren’t just being “careless.” They are choosing to operate below the safety floor their own peers established.
Why Your “Signed Waiver” in the Town of Copper Canyon is Not a Shield
The first thing the insurance adjuster will tell you is that your case is over because you signed a waiver. In Texas, they are wrong. While Texas generally enforces waivers for ordinary negligence, the “paper shield” falls apart on three specific fronts:
- The Munoz Rule: Under Munoz v. II Jaz, Inc., a parent in Texas generally cannot waive a minor child’s personal injury claim in advance. Your signature might affect your own rights, but your child’s right to be whole remains intact.
- The Dresser Fair Notice Doctrine: Under Dresser Industries, Inc. v. Page Petroleum, a waiver must be “conspicuous” and use the word “negligence” explicitly. If the release was buried in a twenty-page click-through on an iPad at a busy Denton County park, it probably doesn’t meet the legal test for fair notice.
- Gross Negligence: No waiver in the United States can release a company from gross negligence. If the park knew a trampoline bed was torn or that a foam pit was compacted and they let your child jump anyway, that is conscious indifference. The Cosmic Jump $11.485 million verdict in Harris County proved that Texas juries will look past a waiver when an operator’s conduct is reckless.
We don’t just “handle” trampoline cases. We audit the park’s compliance with ASTM F2970. We subpoena the franchisor’s audit reports to see if they knew the local franchisee was failing. We hire biomechanical engineers to model the energy transfer that broke your child’s bone. We build the case for gross negligence from day one.

The Physics of the Double-Bounce: Why Size Matters
In the Town of Copper Canyon, we see many injuries occurring during “open jump” times where teenagers are on the same court as seven-year-olds. The physics of this are devastating.
A trampoline bed is an energy-storage device. When a 200-pound adult lands on the mat, the springs stretch, storing massive amounts of elastic potential energy. If a 50-pound child is in the “push-off” phase of their jump at that same moment, all that stored energy is transferred into the child’s body.
Under the Nysted 14x rule, the smaller jumper is fourteen times more likely to be injured than the heavier one. The energy transfer multiplies the child’s launch force by up to 4x. The child isn’t jumping anymore; they are being launched like a projectile at a velocity their developing bones cannot absorb.
ASTM F2970 requires parks to operationalize age and weight separation. When an attendant in a Southlake or Denton park is on their phone while an adult and a toddler share a bed, they are violating the industry’s own safety standard. That isn’t an “inherent risk” of jumping. It is a failure of supervision.
Adjacent Attractions: Beyond the Trampoline Floor
Modern parks serving the Town of Copper Canyon have expanded far beyond trampolines. They are now family entertainment centers (FECs) bristling with mechanical hazards.
Urban Air Sky Rider and Zipline Strangulations
Urban Air’s signature “Sky Rider” indoor coaster has a documented chain-wide pattern of failures. From Newnan, Georgia to Illinois, children have been strangled by harness cords or have fallen when attendants failed to secure them. In the Lakhani v. Sugar Land Urban Air case here in Texas, a fourteen-year-old fell thirty feet because the harness was never attached.
Altitude Climbing Walls Over Concrete
The Matthew Lu fatality in Gastonia, North Carolina, happened because of a failure on a climbing wall—the same type of wall found at the Altitude location in Fort Worth Keller. The park publicly admitted “human error” and removed the attraction. Many of these walls are installed over inadequately padded concrete. A fall from twenty feet onto concrete is a death sentence or a lifetime of paralysis.
Go-Karts and Mechanical Failures
The recent 2025 fatality of six-year-old Emma Riddle at an Urban Air in Florida involved an electric go-kart that reportedly surged forward without driver input. If your child was hurt on a go-kart, climbing wall, or zipline in a Denton County park, we don’t just look at the park. We sue the manufacturers, like Ropes Courses, Inc. or UA Attractions, LLC.
Catastrophic Pediatric Injuries: The Medical Architecture of Recovery
When a child from the Town of Copper Canyon is injured on a trampoline, the ER bills are just the beginning. We represent the parent who has to watch a surgeon explain why their nine-year-old’s growth plate was destroyed.
- Salter-Harris Fractures: A fracture through the growth plate (physis). If not managed perfectly, the bone may stop growing or grow crooked. This can lead to a decade of orthopedic monitoring, corrective osteotomies, and measurably shorter limbs.
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): Because children’s spines are so flexible, the spinal cord can be injured even when the bones look normal on a CT scan. The industry knows this; most ERs don’t. We work with pediatric neurologists who specialize in recognizing this “silent” paralysis.
- Exertional Rhabdomyolysis: This is a medical emergency we know deeply. We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis. If your child spent two hours jumping in a hot Denton County park without adequate hydration and then developed cola-colored urine and listlessness, they may be in acute kidney failure. We have the medical experts already on retainer to prove this case.
- Vertebral Artery Dissection: As seen in the viral Elle Yona TikTok case, a backflip into a foam pit can torque the neck enough to tear the artery supplying the brain, causing a spinal-cord stroke.
We build a Pediatric Life-Care Plan for our clients. We don’t guess what your child will need. We hire experts to calculate every physical therapy session, every replacement orthotic, every special education aide, and every dollar of lost future earning capacity for the next 70 years of their life.
Call 1-888-ATTY-911. We advance every expert cost. You pay nothing unless we recover money for your child.
Backyard Trampolines and the “Attractive Nuisance” in Town of Copper Canyon
With the large lots and family-oriented neighborhoods in the Town of Copper Canyon, backyard trampolines are everywhere. But many homeowners don’t realize they are sitting on a liability time bomb.
The Homeowner’s Duty
In Texas, a backyard trampoline is a textbook “attractive nuisance.” If you have a trampoline and a neighbor’s kid wanders over and gets hurt, you may be liable even if they were trespassing. Most Texas homeowners’ insurance policies—from State Farm to Allstate—have shifted toward strict trampoline exclusions. If you don’t have a specific endorsement or a high-limit umbrella policy, you could be personally liable for a multi-million dollar injury on your property.
Manufacturer Defects
If the net gave way or a frame weld snapped, the homeowner isn’t the only target. We hold manufacturers like Jumpking, Skywalker, and Springfree accountable. We also go after retailers like Walmart (for Bouncepro models) and Amazon (for Amazon Basics models). Under the Bolger v. Amazon doctrine, these retailers can be held liable as sellers for defective products they put into Town of Copper Canyon yards.
Climate and UV Degradation
The intense Texas sun in Denton County is a silent killer of trampoline safety. Polypropylene nets lose most of their tensile strength after just two seasons of UV exposure. A net that looks fine can disintegrate like tissue paper when a hundred-pound child falls against it. We hire materials scientists to prove that the manufacturer failed to use adequate UV-inhibitors or provide clear maintenance warnings.
The Evidence Clock: Why the Next 7 Days are Critical
While you are focused on your child’s surgery, the park is focused on protecting its margin. Evidence in a trampoline case has an incredibly short shelf life.
- DVR Overwrite: Most park surveillance systems overwrite in 7 to 30 days. If we don’t have a spoliation letter on the manager’s desk this week, the footage of the double-bounce is gone forever.
- The “Revised” Incident Report: We’ve seen parks take an original incident report that admitted fault and “update” it within 48 hours to blame the child. Our forensic discovery protocol pulls the metadata to show exactly who edited the document and when.
- The Vanishing Witness: Attendants are often seasonal workers who quit or transfer frequently. We use a 7-channel ex-employee outreach workflow, including LinkedIn alumni searches and labor-department record pulls, to find the staff who saw what happened before the defense lawyers can coach them.
- The Refilled Foam Pit: If the foam depth was the issue, the park will “fluff” or refill the pit within days of an injury. We demand immediate expert access to measure the depth and density before the scene is altered.
The clock isn’t running tomorrow. It’s running right now. Call 1-888-ATTY-911.
Frequently Asked Questions for Town of Copper Canyon Families
Can I sue if I signed the waiver?
Yes. As discussed, Texas law is very protective of a minor’s right to sue regardless of a parent’s signature. Furthermore, no waiver covers the park’s gross negligence. If the park violated ASTM F2970, we can often overcome the waiver.
How much is my child’s trampoline injury case worth?
Catastrophic cases can reach the “nuclear verdict” range. Max Menchaca got $11.485 million in Houston. Damion Collins got $15.6 million in arbitration. Even for non-paralysis cases, a Salter-Harris growth plate injury requiring a lifetime of monitoring can anchor in the $500,000 to $2 million range. We calculate the value based on a forensic life-care plan.
Should I take the park’s offer to pay our medical copays?
No. This is a tactic called the Med-Pay Trojan Horse. They offer a small check (usually $3,000 to $5,000) that looks like a gesture of goodwill, but the fine print on the back or the attached form constitutes a full release of all future claims. Never sign anything or deposit a check from the park without our review.
Why not just use my health insurance?
Your health insurance will pay for the treatment, but they will also file a subrogation lien against any future recovery you get. More importantly, health insurance doesn’t cover your child’s lost future earnings, their pain and suffering, your lost wages while caretaking, or the cost of future specialized education. A lawsuit is the only way to make your child truly whole.
How do I know if the park was negligent?
We look for specific violations of ASTM F2970. Was the monitor-to-jumper ratio worse than 1:32? Was the attendant on their phone? Did they let an adult jump with a small child? Was the foam pit compacted? We handle the investigation while you handle your family.
What if the injury happened at a neighbor’s house in Town of Copper Canyon?
Texas attractive nuisance doctrine holds homeowners accountable when they have a dangerous condition (like a trampoline) that they know will attract children. We look at the homeowner’s insurance policy and any umbrella layers. If the product itself failed, we sue the manufacturer.
Does it cost anything to hire Attorney911?
No. We work entirely on a contingency fee. We advance all costs—the biomechanical engineers, the orthopedic experts, the court reporters. If we don’t win, you don’t owe us a dime. Your family’s recovery fund stays untouched.
