ya man im 15 now and done 20+ foot waterfalls now but since all i have is a Liquid Logic Pocket Rocket (best freestyle boat ever!) i cant do much bigger then that lol i actually placed 1st at and ASCI tournament and got a mystery neoprene shirt and DVD and im glad to hear that u kayak because its a dying sport and who cares what u can do as long as ur having a blast doing it i if u are from east coast region i strongly suggest going to River Sport Kayak Camp (google river sport... 1st one) that is where i've been goin since i was 8 and the staff is awesome... its like camp Woodward for kayakers its on the Yock River so it is mostly class 3 but they are short rapids so if u have to swim 4 some reason its not for long and hell if u live anywhere near Allentown PA then i'll boat with u
