i can only talk for hunter and windham becuase i have only been to belleayre once. ok so here goes nothing
Hunter Mtn
Big fireman and police scene, town has lots of bars and thats the type of people you usually get there. as for the mountain, has a seperate beginner area so less noobs up hill. they have some nice steep stuff especially over on hunter 3. i usually spend most of my day over there, then you have k 27 to have fun on too if you like the bumps. as for trees, plenty of them to go exploring w/ little cliffs and what not. ok on to the parks. they aren't bad, i personaly only have skied there on shitty ass days and they parks were ok. a few medium size hits, some small ones. plenty of rails. i never found anything set up very well, but then again i have only gone there on shitty as days. as for the pipe, its pretty good, usualy cut smoothe and err, don' tknow the hieght off hand.
Windham
more of a family style resort, only 2 bars in town, lots of fmaily resturants. big on ny business people, chinese, and losts of families. as for trails the main peak is pretty much split into two halfs, to skiers right off the lift is all blacks, steep and fast. wheelchair is one of our bump runs that ironically turns into a race course at the bottom of it. on skiers left off the lift there is a variety of blues to cruise on. nothing really exciting maybe except warpath and wise acres. East peak just got a new high speed quad and a new trail so that will be the place to be. 3 blacks, a blue, and a fun green wanderer to have fun in the woods off of. wing'n'it is another narrow bump run when they leave it. as for parks we have are main park on warmup w/ plenty of rails and jumps, usualy there are 3-4 jumps including a nice large table/stepdown at the end. the pipe is going to be nice this year w/ our new zaugg cutter and pipe groomer from stratton. on top of the pipe is a few cliff drops and usualy a sweet table or step down. the jib park has a bunch of little rails to. we also are planning on a skier x course as well.
as for trees, wanderer is a good one to go exploring off of, and anything between wolver and wipeout is cool
