Oh man, luck guy! Don't know much about the road bike scene, but if you are inclined, get yourself a Mountain Bike. Lot's of great riding in that area. http://www.camba.info/
I'm driving west with a mini-fridge, microwave, clothing, 3 (or, if I get my new road frame built up, 4) bicycles*, and more wheels than you can shake a stick at. Plus some camping equipment, and whatever else I can jam in my car.
*MTB, at least one road bike, and a singlespeed road/TT rig.
-I know about OBRA, and it seems pretty great in terms of the information provided, and general organization. Are there any other sites that are helpful in that regard?
I'm up in seattle, so not much info for you on specifics of teams and/or group rides. [Though, given how awesome the terrain is out there, I'd be surprised if there weren't a fair number of options. For teams, I would guess you're going to end up with one of the Portland or Vancouver, WA based teams, Hood River is pretty small.]
The real reason I'm replying is just to add that you should also check out the Washington Bike Racing site. Since you're right on the state line, a lot of WSBA races will be as close to you as they are to us (us meaning seattle metro area), if not closer - there are (regionally) important stage races/omniums in Wenatchee, Spokane & Walla Walla, lots of road races in the south puget sound/chehalis area, etc. Of course, that's in addition to all the great races down in OR...
