Yep a trip that stopped in Hood River for a couple of days, then maybe Sun Valley/Ketchum for 3 days where you can experience lung burning climbs getting out of bed since Ketchum is at 5500' elevation, but has lots of great single track and then south to UT to ride until you're almost too tired to drive home, maybe leave an extra day or two for the return trip so you could ride some of the Mt.St.Helen's trails on the way back to Seattle.
