I think people feel it is too hard to get sponsored,so they don't even try.....Normally it's noobs who are mad about getting sponsored 'i haz lernt to trials hop in an hour,will i gt sponserd in the future??' And things of that matter....People probably feel the rewards aren't worth the effort either,like somebody has mentioned about free bikes,i think that's what noobs think they will get and when they find out they wont the idea begins to lose the fancy appearance,Meh im probably talking out of my arse. zoo baby!
