you could make a good argurment though, seeing how other sports can be just as dangerouns to unaware passerbys, but i just don't think it's worth fighting in court about.
Like golf? More people get hurt playing golf then paintball true fact. I mean if someone hits a golf ball hard and it hits someone in the head the person hit would probably die. I wouldnt worry about the cops if u were playing in the woods. I mean why would they waiste there time walking all the way out there to bust some kids having fun?
you are aloud to go out there only if you dont leave any trace behind after you play the paintballs are fine because they will decompose but dont leave anything or dig holes or anything like that but you wont get in trouble if you do those few things.
Just don't go paintballing in "abandoned(sp?)" buildings with nosy neighbers around. My and a couple friends went out behind our house, and found some run down little buildings, we couldn't resist, we had to play pb in houses, we almost got in serious trouble, ouch...
