Do you mean the car scene or something else? There are car enthusiasts here but Seattle overall is a crappy city for cars. See this thread: http://www.m3post.com/forums/showthread.php?t=794925
Everyone on this board that I've met is great and people at the track are nice and respectful. It's a good car community with different groups depending on what you're into. Seattle and the NW is about as opposite of So FL as you can get though so if you do head out this way, be ready for some culture and weather shock. What's the job? BTW, this board is pretty dead usually. You can also try the E90post NW board but they're "different"
