I belong to a group called SactoMetro, it's a Street Team for Etsy shop owners in the Sacramento area. All you have to do to join is have an active Etsy shop and live in the area. Just go to http://groups.google.com/group/sactometro and request membership.
While the group has been around for a while it kind of went stagnant, but we have flushed the folks who weren't active and are now accepting new blood. We are revitalizing this group. We want to have somewhat regular get-togethers and do some shows as a group as well.
And if you haven't heard of Etsy but want to sell your handmade goodies online you really need to check it out!
