Bremerton and Yakima both have a good "grass-roots" feel to them and really cater to the sportsman racer. Not too far to the south lies Woodburn, OR. (3 hr drive, just south of Portland), which is a great track with a solid scene. Make a point of getting down there when you can, you won't regret it. I've never raced at Spokane, but is a 4+ hr. drive from the Seattle area. Pacific is a great facility, and is clearly the top option if you live in the greater Seattle area. You'll have options.

Congrats on the move, and welcome to the Northwest!
