Rules? What rules?

The car must have a minimum of three wheels in contact with the track.
The car must be powered solely by gravity (no kinetics, no wind - no propulsion).
The car must have functional brakes (no Fred Flintstone brakes).
You cannot spend more than $300 on your car.
The car cannot be wider than 66.6 inches.
The car must include a large eye bolt positioned to allow the car to be towed back up the hill - make it sturdy.
Lugge boards, skateboards, or similar vehicles do not qualify as a car.
YOUR CAR WILL BE INSPECTED AND HELD TO A “WORKMANLIKE” STANDARD. UNSAFE CARS OR CARS IN VIOLATION OF THESE RULES WILL NOT BE ALLOWED TO RACE.

Each person in the car must have a helmet that is secured to his or her head by a strap or other reasonable means - full face helmets are recommended.
All drivers, racers and team members must sign a liability waiver.
IF YOU DON’T HAVE A HELMET OR YOU FAIL TO SIGN THE WAIVER YOU WILL NOT BE ALLOWED TO RACE.

All Drivers must be in their car at the starting line.
All cars get a ten yard push start. Each team must provide their own designated pusher. Pushers who step over the ten yard foul line will disqualify their car for that run.
No more than three people are allowed in a car while racing. The designated pusher may not be a racer, driver, or otherwise jump onto the car.
No contact with other cars is allowed in the ten yard push zone, or within line of sight of the finish line - ANY CAR MAKING CONTACT IN THESE ZONES WILL BE DISQUALIFIED FROM THE EVENT AT THE SOLE DISCRETION OF THE ORGANIZERS.
Score will be kept by averaging race times. If you fail to make a race or are disqualified from a race your time will be entered as three minutes (3:00).
No pyrotechnics, fire, or fireworks are allowed in the park or as part of any car.
Liquid water is the only acceptable weapon or projectile which may be deployed from or against any car (water balloons are acceptable).
