Pros: Its well worth it, I loved it back in 2004. Our teacher would have us do shit like 3 contests coming down cliffs above 3 bears and bush taps off high T drops.
Cons: We did have to ski bumps alot, which was G a Y. And we did have this one lame instructor teach one day that was like "follow me" ...and he blew ass, got schooled by half the class and then had us go home early because we wouldn't listen to him.
I have heard not so much ridge hiking in class these days??
