I am in the waukesha area, just west of Milwaukee.
Milwaukee has a club the circle-masters. I am not a member of the club yet. Their meeting are on Saturday afternoons and I coach youth sports, Saturdays are real tough.
They hold a stunt contest on fathers day. There are several others in the Milwaukee area that fly too.
There is a good hobby shop on the east side of Madison the hobby horse I believe. Mostly RC, but some control line stuff. There is a good control line shop in Milwaukee, kind of junky, but lots of parts and out of production kits.
Madison has a several active RC clubs, so that would be a place to start. Also there is a very good combat pilot about 30 minutes west of Madison in Boscobel, he holds 2 contests a year.
Oh yes, Welcome to the PRM (the people's republic of Madison). Enjoy the high taxes, beer and cheese.

Madison has been described as an island of liberalism surrounded by reality. Typical of a college town/ state capitol. It's a fun town, the summers are great the winters stink.
