I'm afraid I'm not that close to the Twin Cities to know much about user groups there. Now I'm attending Minnesota State University: Mankato and I know of no user groups in Mankato at all. Listen to Sidewinder though, he used to be from Minneapolis (or so he wrote on his user info here) so he should know the area pretty well.
I'm originally from Iowa and the last user group I attended was in Cedar Rapids (which was quite a drive from Waterloo).
