Let me make another plug for the Southern Michigan Audio Club (SMAC), which meets every month in the metro Detroit area. We even have our own sub-form over at Audiokarma -

The date/location of the Jan 2008 meeting has not been decided yet, but usually, somebody steps up without fail. We have about 40 or so members (maybe more). Around 20-25 show up for the GTG. The SMAC has been meeting without a break for almost 2 years.
Pete hosted a GTG for the SMAC in September 2007 - it was great. I hosted one in July 2007. It is a lot of fun. There is usually a music swap. Sometimes, equipment comparisons take place. But there is always good company, good music and liquid refreshments to fortify yourself.
