I'm about to relocate to Seattle, and I was curious as to whether or not there was much of an auto-cross scene up in the PNW, and if so, how active the region is?

I did one last week thru Audi Club NW the website where all upcoming events is motorsportsreg.com. It was held in Bremerton, all three of the M's in my pic were there. It was a Audi sponsored event, and everyone was super nice. There were a lot of different cars not just Audis. Miatas, Old Mustangs, a PT Cruiser, a few Mini's, even an Audi AllRoad, and S8. I'm doing the one in Monroe on June 10th also thru Audi NW, it's $60 for all day on the 10th. Look at the website for any required memberships etc. BMW has some events that they sponsor also this summer.

Ok, so events are held routinely, got it! This is good to hear.
