Not that I've found yet, Mopar. There's one not far from me in bowie (I'm western AA co), but they never answer email and the website seems to have fossilized about two years ago.
Looks like there's a great club up in Balmer, but it's a bit of a haul for me and I just haven't had a chance to check it out yet. I do plan to find a good club one of these days though.
Here's the club finder directory from the American Bonsai Society site:
