Your on the wrong side of the mountains. I don't know about eastern Wa., but on the west side, their's 400 car shows in the Seattle-Tacoma general area during the summer, plus numerous hangouts where 'Stangers meet on a weekly basis.
I'm over here in Clarkston, Wa. Not to many mustangs around here. I do the Lewiston Hot August nights every year. It's a Friday night cruise and then show and shine on saturday. About 300 cars. I want to do some more car shows and get my car to the track in Spokane and Walla Walla and maybe even Tri Cities. Got to get it to the dyno first.
First of all, i send my condolences. I see you're from Yakima. Second of all, there really isn't a lot that goes on in the Spokane area that actually makes it to these boards. I've been tempted to leave notes on nice Mustangs I see, telling them to join Stangnet.
