Washington state, especially the NW, is the greatest! I was yanked away as a kid (10) and always wanted to come back during the 20+ years I was gone. It's beautiful, one of the last ecologically sound places left in this country, animal friendly, not too expensive (unless you live in the heart of one of the big cities), great public transit (important to me as I cannot drive), and fair economy. Not sure about medical related jobs, but there are a TON of hospitals, clinics, and medical type places so I would imagine you'd be good to go.
Cost of living: pretty good in the suburbs. I live in Kent, which is about 23 miles south of Seattle proper, and two of us currently are living on about $1200 a month. My partner just got a new, better paying, job, so that'll be going up...but we aren't doing too badly. I know that costs can be sky high in Seattle itself, though, so it all depends on where you choose to live.

The Weather: Not as bad as many people say. Because we still have a good ecological balance, we actually have all 4 seasons. It's cold in winter but not extremely so, windy in spring but still fair, warm to mildly hot in summer but not triple digits, and the main wetness comes in the fall. Yes, it is gray and overcast a lot, that one is true...but I think it just adds to the natural beauty of the area.

Like living here: Like??? I adore living here. The PNW is the best! Minimal natural disasters (yes, we have two volcanos nearby but they're currently dormant), fairly even weather, the Ocean, 3 mountain ranges, Mt. Rainier, and trees trees trees!

Pros: read the above. Great mix of rural to urban to fit any taste. The most urban, of course, is Seattle followed by Redmond and Bellevue. The most rural, on this side at least...probably Enumclaw/Bonney Lake, and Yelm, Spannaway etc. The southern sections of the NW corner.

Cons: Hmm... I'm not sure. If you're used to the political scene in OK, then you might want to stick to Eastern WA. Otherwise... I can't really think of many cons.

Pictures: Hmm, I need to get more...but here ya go.
