MA has 5 small-medium sized hills, around 800-1000 ft vertical. Catamount (on NY border), Berkshire East, Jiminy, Butternut, and Wachusett.

There are a number of tiny places scattered about. Ward, Nashoba, Blue Hill, Bousquet, Blandford.

Other commenters are correct that most people go to VT/NH/ME to ski "for real". But no harm in trying the others while they still exist (because lord knows they probably won't in 15 years!)
