I'm from Boise and don't get over to your neck of the woods much.  My wife and I are going to be in Seattle, though, over the 4th of July.  I thought it would be fun to drive back through Oregon, starting around Portland.  Along the way I'd like to stop and pick up some chunks of wood for turning, especially woods more common to the area, eg madrone, laurel, oak( black, white) and others.  Where would be good places to stop?
