I have friends that rent Snowmobiles. They teach them basic safety before they head out. Start, Go ,Stop. Any damages are your responsibility and lies cost you double. They sign up and lie their asses off. My friend and his friend are getting rich(the repairman). Some basic training would be nice, I.E. red means left(port) you get the picture. One reason I spend my winters In Missouri/ Arkansas is because I can't sit in an Ice Shanty anymore with out the worry of a 100+ sled running over you. It happens.
