Dude, if you took me on a black run my first day I would kick your ass. Maybe your black runs are not like our black runs but come on. That is the dumbest thing I have ever read. I also think learning just to be on an edge is dumb, there is so much more then just making it down the hill.
I think I paid 120 bucks for 3 lessons and 3 days of rentals when I first started. Boyfriends, husbands, do not teach your mates to ride. Hire someone or put them in a class.
