My guess is that you're close enough to Madison that you'll do better to meet up with people there, but good luck, and if you ever decide to set up a comp west of Madison (how about Richland Center or Viroqua? Maybe La Crosse?) I'll probably come.
It is, but it's just about 40 minutes away for me too. La Crosse, though, is right on I-90, and pretty close to halfway between Madison and Minneapolis. If I was going to put the effort into organizing something I would go with Viroqua which is about 20 minutes for me, or try for something really in the middle of nowhere just to see if people would come to Seneca or Eastman. I bet I could rent out the basement of the Southwest Prairie Lutheran Church for a Saturday. That would be interesting and remote (and most importantly exceptionally convenient for me).
