OK. First off I'm going to say,
fuck your rules , BMX isn't about rules. BMX USED TO NOT EVEN BE CONSIDERED A REAL SPORT! IT WAS A HOBBY/LIFESTYLE NOT SOME FUCKING FOOTBALL JOCK SHIT. Every time i hear someone say "oh you one upped me" or "you did that before me" i think "wow this dude really takes BMX too serious." You see, when you ride and see somebody doing something, i myself usually feel somewhat inspired to do something on the ridden obstacle and give it a try from my perspective and/or learn something new or even brush up on an old trick, last thing on my mind is "gee golly i hope this kid doesn't mind me riding my bike on this obstacle he cant wallride". I personally like being one upped, it makes me see what i need to do or as previously stated, inspire me to do something. Whats ruining bmx is the fucking losers trying to tell people what is "fun". Do you think i REALLY need someone to tell me how to have fun? Are you fucking kidding me? I wouldn't ride anymore if i wasn't having fun. I wouldn't get out of bed if i didn't have fun. Half the times the fun police are the worst kind. These whack fucking old grumps trying to tell you how to ride to have your own fun in an individual "sport".
I say do what you want, but FUCK THE FUN POLICE. ride for yourself, everyone will always have an opinion on whats proper but it doesn't make what they have to say any more valid in an individual "sport" like BMX.
