Here's another thing that may be helpful... this is a gbody site, but, many (most?) Of us have other car passions too...
You can find the most enthusiast friendly neighborhood, BUT, if that area you're moving to crushed most of the kinds of cars you liked years ago, and everything that's left is full of rusted seized bolts that snap and bloody you knuckles at every turn what good is that?
Pick a spot, look on its craigslist then add a bunch of surrounding areas to see what kinda cars are around/ available in the decent radius.
If you love gm square body trucks, but it doesn't show hardly anything for sale or in the parts section, it's a harder area to pursue that particular hobby in....
