Welcome to Ukulele Underground, Sneaky!
You'll want to attend the Nashville Ukulele Society meetings. Players of all skill levels are welcome. There will be another gathering in about three/four weeks. Visit the blog for an address you can write to and ask to be added to the mailing list.

The blog has been essentially dismantled in favor of the Facebook page, but it's a good place to add your name to the mailing list if you are not on Facebook:

We hope to see you there!
