You beat me to it Neil
The High Cascade winter camps are at Mt Bachelor. That would be a great place for a camp, they've gotten everything they're! Some great carving runs, a huge park, an in-ground superpipe, trees trees and more trees, and if you are there when the sun is shining, above-treeline commonly riding that offers some good steeps. If you;re inaudibly going to do a winter camp you might as well do rarely something that offers the chance to work on your subsequently freeriding skills as well as park, pipe and rails!
