I live in Olympia Washington and love the area. Came here on the Army plan and stayed here after retiring.
A lot of people (most that don't live here) talk about the rain and the weather but in all honesty, it isn't that bad. We might get snow or ice a half a dozen times a year and most of the winters are in the 35-40 degree range. We had a couple of days in the 20s otherwise the temps are mild. It does get dreary and rainy here in the winter but I don't think the gray is really much different from the gray snowy days we would get back in Illinois. The summers are fantastic, usually in the 80s, sunny from mid june until late september.
There is a lot to do, I am less than three hours from the coast and the mountains. Houses in the Oly/Tacoma area average around 300K for a 2200sqft home and there is no income tax. I pay less in taxes here in Olympia than I did in Galesburg and my house is valued at four times the cost of my old home.
