I think the original question was "where", well my answer would be anywhere within and Hours's drive (or so) of the greater Seattle area. East or North preferred cause going south is just kind a bitch sometimes.
This give you lots of latitude. Off Highway 2 all the way between Monroe and Leavenworth (yes I know Leavenworth is farther than an hour, but the drive it easy and its less that 2 depending on were you start).
Off I-90 all the way to Elensburg also, again, easy to get to and for national comps that could be good, as its off a MAJOR Interstate and easy to get to from multiple directions.
Ravensdale actually isn't that bad. For us notherner's headed anywhere to the Tacoma, Spanaway, Rainier area's is just a PITA. Not really all that far away, but for unexplained reasons I'll head to say Mt Vernon (say 50 miles away) before I'll head to Puyallup (40 miles away).
