yeah, not really any I know of. I am about to get my 335i in a few days now so I am new to the BMW crowd, but I moved here a few years ago with a 350z from Texas and there are no clubs at all. The scene around here lacks. Unless you like the "street racing - high school crowd. not too many enthusiasts...
I definitely miss hanging out with my car buddies in Texas, there are alot there.
we can try to start one!
