Rick Bradley is setting up a dynamic languages group in Nashville:

I've set up a Google Groups mailing list for the Nashville Dynamic Languages group "which is a pretty informal social and technical group of people (predominantly located in Nashville) who are interested in dynamic programming languages ( Smalltalk , Ruby, Lisp, Io, etc.). We had a get-together earlier in the week to test the waters and had a really good turn out. There's a heavy Ruby (+ Ruby on Rails) bent, but there's a lot of interest as well in other languages.

There should eventually be a website at nashdl.org.
