I was in the park b4 twin-tips pretty much existed, and even tho it was a bit harder to do tricks on old k2s, i could still manage a few grabs, 3's, and crosses.  The snowboarders, would yell get outa the park, and throw snow at you when u would hit the lip.  Most of us pbly have been on the verge of a fight between a snowboarder, but the fact is, the guys that were yellin the most, they would just camp at the top of the rail, while there were only 2 or 3 good ones, pullin backflips, and such, the others were just sayin i can do that.  The funny thing is that the best snowboarder always seemed to have the most respect for ppl tryin to freeski.  We do come from the same mold kinda thing.  The only posers 'on' the hill are those, 'i can do that'
