From their facebook page: Brandon Bootleggers is a club for people who brew their own beer or are interested in starting. We are based east of Tampa, FL, and meet the 3rd Weds of every month at O' Briens Irish Pub. Dues are $15/year per family. All members are encouraged to attend meetings, and bring whatever they have on tap to share (or bring a craft beer to share, or just come and enjoy).
They are associated with a homebrew shop of the same name.
Booth's brewing is another homebrew shop in Brandon, closer to Tampa. I know they have classes there, I'm not sure of any club affiliation.
I have run into the Special Hoperations guys a few times at local events and they seem cool too.
Can't speak to any others.
Hope this helps.
