you need usasa or ussa and a coach to go. Coaching fee is 50 a day (i think) and ramp fee is only like 30 (again i think) If you already have ussa or usasa its not a bad deal i would reccomend at least three days on the ramps though it takes a full day just to get used to them its like riding on glair ice
hit the water ramps up this past weekend. spent both saturday and sunday there. it was dope. i rode the ramp twice and then just started dialing in the tricks. the price is a little high. 50 for a coach and 18 for pool fee (68 total) but its worth it. they have dope trampolines too.
