MSL used to have a lot of comps..mostly snowboarding. i haven't heard of anything recently though. Since they are privately owned they may have cut back due to insurance reasons. Snow Valley usually has a small halfpipe/big air series and there is always SOD freestyle big air/pipe comps. Blue Mnt. is going to have some larger (less amaturish) comps...keep checkin this site as they get announced her usually.
The troll stole my Santa!
I skiied there a couple times, if you guys are part of the ontario skiiers cult go into the message board and i started a forum to post comps. So if you here of any at your local mountain keep everyone posted.
