“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.”

That is how Kaitlin “Kati” Hill described the second her three-year-old son’s life changed forever. It didn’t happen in a high-speed car wreck or a freak natural disaster. It happened at a trampoline park during a supervised “Toddler Time” session. Her son Colton suffered a broken femur, spent months in a body cast, and left his parents with a haunting realization they shared with ABC News: “We had no idea. We would have never put our baby boy on a trampoline if we would have known.”

In City of Canyon, families frequent local attractions and nearby centers like Urban Air in Amarillo looking for that same brand of “safe family fun.” You sign the waiver at the kiosk because the line is long and your kids are excited. You hand over your credit card and watch your children run toward the foam pits and dodgeball courts. You trust that the padding is thick enough, the attendants are trained well enough, and the safety rules are followed strictly enough to keep them out of the hospital.

Then the double-bounce happens. Or the harness on the climbing wall isn’t secured. Or the foam pit bottoms out onto the concrete subfloor.

Within seconds, the laughter stops. The “worst scream” happens. And before the ambulance even reaches the Northwest Texas Healthcare System or another regional trauma center, the park’s risk management team is already at work. They aren’t working to help your family; they are working to protect their margin. They rely on the piece of paper you signed to tell you that you have no rights.

They are wrong.

At Attorney911, we have spent more than 25 years making corporate defendants pay for the business decisions that maim children. Led by Ralph Manginello, our firm brings federal court experience and a track record of multi-million dollar results to families in City of Canyon. We know exactly what the parks in the Texas Panhandle are hiding, and we know how to pierce the corporate shields they use to hide the money.

Why a Trampoline Injury in City of Canyon Is a Business Decision

A trampoline injury is never just an “accident.” It is the predictable output of a system designed to maximize revenue while cutting costs on safety. When your child is injured at a park serving City of Canyon, it is almost always because of a choice made in a corporate office miles away from the jumping floor.

The commercial trampoline park model is built on high throughput. On a hot Saturday afternoon in Randall County, when the West Texas wind is blowing and indoor play is the only option, these facilities fill to capacity. To maintain their profit margins, parks often operate below the safety floor established by their own industry.

The industry wrote its own rules—ASTM F2970—specifically to address these risks. They know that when a 200-pound adult lands on a mat while a 60-pound child is jumping, the energy transfer can multiply the child’s launch force by up to four times. The child isn’t jumping anymore; they’ve been turned into a projectile. This is physics, not bad luck. The park knew it could happen, and if they failed to separate those jumpers by age or weight, they chose to accept that risk on your child’s behalf.

We see the same patterns in our active $10 million lawsuit involving rhabdomyolysis and acute kidney failure. That case involves institutional-defendant accountability—the same failure to monitor, failure to warn, and failure to adopt protective protocols that we see in City of Canyon trampoline cases. Whether it’s a muscle-breakdown injury from ninety minutes of continuous jumping in a 90-degree indoor facility or a shattered growth plate from an unmonitored court, the negligence is systemic.

The Evidence Clock Is Running in Randall County

If your child was hurt at a trampoline park near City of Canyon, the most important thing you can do is realize that the evidence is already evaporating. The park knows that most families won’t call a lawyer for weeks or months. They count on that delay.

  • Surveillance Overwrites: Most park DVR systems in the Texas Panhandle are set to overwrite footage in as little as 7 to 30 days. If you don’t secure that video immediately, the only record of the accident becomes the word of a teenage employee versus yours.
  • Incident Report “Revisions”: We have seen cases where the original incident report filled out the night of the injury contains damaging admissions from staff, only to be “finalized” or “updated” forty-eight hours later to blame “guest error.”
  • Kiosk Metadata Purges: The waiver kiosk databases often purge version history and audit trails on rolling cycles. We need to know exactly what screen your husband or wife saw, what font size was used, and whether the electronic signature was even valid under the federal E-SIGN Act.
  • Witness Dispersal: The average tenure of a trampoline park attendant is less than nine months. By the time most people file a claim, the sixteen-year-old who was on his phone instead of watching the court has already quit and moved on.

Our firm doesn’t wait. When we are retained for a City of Canyon trampoline injury, our spoliation letter goes out via certified mail within 24 hours. We demand the preservation of every camera angle, every maintenance log, every training file, and every version of the waiver. By Day 10, while the park’s insurer is still trying to get you to give a recorded statement, your case is already forensically protected.

Texas Law and Your Rights: The Waiver Is Not a Wall

The first thing the insurance adjuster will tell you—the “friendly” caller who sounds so concerned about your child’s recovery—is that you signed a waiver, so the park isn’t responsible. In the State of Texas, that is a half-truth designed to make you go away.

Texas courts have clear rules that can render these waivers useless. Under the Dresser Industries v. Page Petroleum doctrine, a waiver must be “conspicuous” and it must satisfy the “express negligence” rule. If the release language was buried in a twenty-screen iPad click-through, or if it didn’t specifically and clearly mention the word “negligence” in a way a reasonable person in City of Canyon would notice, it fails.

Moreover, the landmark Texas case Munoz v. II Jaz Inc. established that a parent’s signature generally cannot waive a minor child’s personal cause of action. Your child didn’t sign that paper. Your child didn’t consent to the risk. And even if you signed it, you cannot be forced to indemnify the park for their own negligence against your son or daughter.

Most importantly, no waiver in Texas protects a park from gross negligence. In Harris County, the Cosmic Jump verdict of $11.485 million proved that when a park knows of a defect—like a torn mat or a depleted foam pit—and does nothing, the waiver is irrelevant. The jury found gross negligence and awarded $6 million in punitive damages specifically to send a message to the industry. We are here to send that same message for families in City of Canyon.

Mapping the Attractions: Where These Injuries Happen

Every attraction at a park serving City of Canyon has a signature injury mechanism. We build our cases by matching the physics of the attraction to the violation of the ASTM standard.

The Double-Bounce on the Open Court

This is the most frequent source of catastrophic pediatric fractures. ASTM F2970 requires parks to separate jumpers by age and weight. When a park allows a teenager and a toddler on the same bed, they’ve violated the standard. The energy transfer from the larger jumper creates a force the child’s developing bones cannot decelerate. We routinely see comminuted femoral shaft fractures and Salter-Harris growth plate injuries from this exact scenario.

Foam Pits: The Highest Catastrophe Profile

Foam pits look soft, but they are often the most dangerous places in the park. If the foam cubes have compressed over time or the pit hasn’t been “fluffed” according to the manual, a jumper can bottom out onto the unpadded concrete floor. This leads to cervical spinal cord injuries and SCIWORA (Spinal Cord Injury Without Radiographic Abnormality), where the cord is damaged even if the bones look normal on a CT scan. The industry knows this; it’s why most major chains are desperately trying to replace foam pits with airbags. A park that still uses a foam pit in City of Canyon is choosing a cheaper, more dangerous landing surface.

Harness Failures: Climbing Walls and Ziplines

A fall from 20 or 30 feet because an attendant failed to clip a lanyard or an auto-belay system failed is never an “accident.” In the Matthew Lu case, the Altitude park publicly admitted “human error” killed a twelve-year-old child. In the Lakhani case in Sugar Land, a harness was strapped but never attached to the fall protection. We look for design defects in the equipment and systemic training gaps in the staff who are supposed to be “certified” but often have only two hours of training.

Ninja Courses and Stunt-Tramp Injuries

Parks like Urban Air and specialty ninja gyms often encourage “stunt culture” through their marketing and influencer partnerships. But when a child attempts a maneuver they saw on the park’s TikTok and lands on an unpadded frame, the park blames the child. We use the park’s own marketing against them. If they sell the stunt, they own the injury.

Catastrophic Injuries and the Pediatric Lifecourse

A “broken leg” at age seven in City of Canyon is a different medical reality than a broken leg for an adult. Pediatric bones are biomechanically distinct. The growth plate—the physis—is the weakest part of the skeletal system.

A Salter-Harris Type II fracture might look like it healed on an X-ray six months later. But at age twelve, when that child hits a growth spurt and one leg doesn’t grow straight or grows shorter than the other, the real damages manifest. We work with pediatric orthopedic surgeons and life-care planners to forecast these costs. We don’t just ask for the ER bill; we calculate the next ten years of orthopedic monitoring, the potential for corrective osteotomy, and the lost earning capacity of a child whose mobility is permanently impaired.

This medical depth is what we bring from our $10 million University of Houston rhabdomyolysis litigation. We understand the myoglobin cascade, the renal tubular damage, and the lifetime implications of acute kidney failure. We don’t settle based on what the adjuster says your child is worth; we settle based on what the medicine proves they will need.

Who Is Really Responsible? Piercing the Corporate Stack

When we sue a park that injured a City of Canyon resident, we don’t just name the local LLC on the lease. We perform corporate archeology on the entire stack:

  1. The Operator LLC: Often undercapitalized with a $1M limit.
  2. The Franchisee: The local owner who may own multiple locations across the Texas Panhandle.
  3. The Franchisor: Entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings, who set the rules but try to disclaim the liability.
  4. The Corporate Parent: Sky Zone, Inc. (renamed from CircusTrix) or Unleashed Brands, often backed by private equity firms like Palladium Equity or Seidler Equity.
  5. The Manufacturers: The vendors who sold a defective net or a triangular Wipe-Out trampoline that has a dangerous bounce response.

Our team includes an attorney, Lupe Peña, who previously worked on the defense side. He knows exactly how these insurance towers are built and which “additional insured” clauses to trigger to reach the tens of millions of dollars in umbrella and excess coverage. We go upstream because the money—and the responsibility—is always upstream.

Frequently Asked Questions for City of Canyon Families

Can I sue if I signed the waiver at the park?

Yes. In Texas, waivers are highly scrutinized. They cannot bar claims for gross negligence, they often fail the “conspicuousness” test, and under Munoz v. II Jaz Inc., they generally cannot waive a minor’s right to sue for their own injuries. The waiver is the park’s defense; it is not the law.

How much is a trampoline park injury settlement worth?

Value depends entirely on the injury and the liability evidence. Catastrophic spinal cord cases have resulted in awards exceeding $15 million (see the Collins arbitration). Traumatic brain injury verdicts, like Cosmic Jump in Houston, have reached $11.485 million. Even fracture cases with growth-plate involvement can anchor in the $500,000 to $2 million range because of the long-term medical monitoring required.

What should I do if the park manager tells me not to call 911?

Call 911 yourself immediately. Multiple reports across Texas suggest some parks instruct employees to downplay injuries to avoid creating a record. This is a tactic designed to protect the park, not your child. If you have to call 911 yourself, that fact becomes powerful evidence of the park’s conscious indifference to your child’s safety.

how long do I have to sue a trampoline park in Texas?

The standard statute of limitations is two years from the date of injury. For minors, the clock is tolled until they turn 18, giving them until age 20 to file. However, you should NEVER wait. The evidence clock (surveillance video, witness memory, equipment condition) runs out in weeks, not years. Call us now to preserve your case.

Does it matter if my child was double-bounced by an adult or another kid?

The park’s duty is to supervise and separate. ASTM F2970 requires age and weight segregation precisely because double-bouncing is a known hazard. It doesn’t matter who else was on the mat; it matters that the park’s attendants failed to enforce the single-jumper rule or the weight-class rule. The park is liable for that failure.

What if my child has dark urine or severe muscle pain a day after jumping?

Go to the emergency room immediately. This is a hallmark sign of exertional rhabdomyolysis, a condition where muscle fibers break down and poison the kidneys. Most doctors miss this on a first visit. Ask specifically for a creatine kinase (CK) blood test. We are currently litigating a major $10M case involving this exact pathology and can help you document the connection to the park session.

The park offered me a refund and a “medical payment”—should I take it?

Not without a lawyer. This is often the “Med-Pay” trap. They offer you $3,000 to cover your deductible, but the fine print on the check or the signature form you sign to get it acts as a full release for all future claims. You could be signing away a multi-million dollar recovery for the price of one ER visit.

  5. Stop Posting: Do not put photos of the cast or the hospital on Facebook or TikTok. The defense is watching.
