everybody starts from somewhere give them a chance at least they are trying. Wait to you feel that same way because i do when i ride the breck park with all the pros who can throw down huge. Only rag on people when they are dicks.
Ya i know that place is so dam crowded i dont even ride it any more i think its to much of a hassle. It sucks because im trying to get better at park riding but its so hard to learn new stuff while dodging people and having to race to drop in.
Sounds like you just need to commit to it. Try to look under your shoulder to spot your landing and dont worry to much those back yard jumps sometimes suck I rember last year on a back yard jump i had the same problem.
