I have lived in the Seattle area for many years and know of several clubs in the area. First of all what scale do you model? Second what area of Seattle are you located in? I am an N scaler and am a current active member in the United Northwest Model Railroad club. I also know of the Mt Rainier N scalers (they are located in the south end mainly around Olympia). There are several others I can get you mor einfo if you want it.
