dont let the rain stop you Z! you can go through mud just nothing deep. i used to have a z400 and now have an ltr450, as long as you have enough speed you'll go through it. and if you get stuck, that's what you got your buddies for haha
(since we ride hard) i think the reason they kick us out is because they're liable for any rider that gets hurt...so this means they can get sued. but with paintballing, you can't really get hurt by getting hit with little paintballs
