I have skied big mountain, now known as whitefish, and it was amazing!!! Granted it is the only place ive been out west but the trees/poweder were awesome! You never had to wait in lines and everyone was so nice. None of the annoying crowds you get from the city, jersey, LI etc...like around here. My only negative about it was that it was foggy the whole time we were there. In the woods it was fine but i was kind of dissapointed that i couldnt see the amazing views ive heard about. Go check it out, you wont be disappointed!
