I go to okemo in central vermont.. it is by far the best mountain i have found on the east coast so far..
All my snowboarder friends from school would go there too, it is 100X better than stratton mountain and it is really clean, well maintained, has great snow, and ALOT less people than stratton (or any other east coast mountains for that matter), its also a pretty damn big mountaint, with a shitload of lifts and different trails, its mad fun.
115 trails, slopes and glades
18 lifts, including 9 quad chairs (5 high speed detachable quads), 3 triple chairs and 6 surface lifts.
2,200 feet (highest in Southern Vermont)
