People that get completely trashed out on the trails, and pay no mind to any kind of safety, and trash the trails. When dealing with vehicles, they are just not safe to be around.

I do drink on the trails, but I take my trash with me, and pay attention to the safety of those I'm wheelin with.

I see. we get a different kind of problem over here, burnt out cars left in the lanes (trails) usually they've been stolen by "joyriders"
