Carrabassett Valley Academy (CVA) up in sugarloaf has a sick freeride program, they've got this building right next to school with tramps and a skatepark you can use all the time too.

Also, not many people know that NSA and Northwood School here in Lake Placid NY have freeride programs too, plus being right in placid we get training time all fall after school on the water ramps, then after the world cup event in the winter we get to build whatever jumps we want on the arial hill. Whiteface doesnt have the best park, but it's pretty good and we're constantly traveling around to other areas too. The coach is Justin Perry (films for meatheads). Just something to check out-

NSA is more of a sports-oriented school, where Northwood is more of a private school. I went to northwood for 2 years before dipping out to do online school
