It's based out of Oregon. The traditional winter camps have been at Mt. Bachelor (sick, sick, sick mountain). The summer camps are, of course, based out of Mt. Hood (Government Camp, OR)...pretty much the only place in North America that you can ride all year round.
This year, however, I believe they are doing a few "remote" camps in Tahoe, but I don't think they will be as good as the Oregon camps where they have their own facilities, lodges, skateparks, etc. etc.
Board harder than you've ever boarded before during the day...party at night...all in August. Can't ask for much more.
