in south Minneapolis was fun to visit last Saturday. They combine education, PC recycling and resale, and Linux introduction. They rely on volunteers. They install XUbuntu Linux for new users. Speaking with a long time volunteer, he seemed not to have heard about TCLUG. My big urban adventure also included an inquiry regarding anybody doing circuit board fabrication. I was referred to TwinCities Makers dot org, a few blocks from Free Geeks. Their web site describes interests that include soldering and Arduino. Both community groups were housed in nice old industrial structures.
