There is a Club Finder on the entry page that gives clubs near you, but I don't think that there is a big list of all of them to just read.
If you are looking for something kinda like an individual model airplane club ... there really isn't one. MWC, IRCWCC, and Treaty are all USA wide type clubs with members scattered around the US. There are groups of captains in various places, such as Minnesota that would be the closest thing to an individual fast fun club. There are exceptions though. Big Gun actually has individual clubs, such as the Texas guys. The club/people finder here on the web site is a good place to start to find someone nearby to hook up with. Also, the individual format web sites normally include a listing of members or a way to find members closest to where a person lives.
