Actually, that's not a bad idea. About three years ago, we had a little mini confluence at my place (back when I had only 12). Only got about five guys show up, but we had a great time for the afternoon. Bill Henshell came up from Chicago, and Ted Williams came from near Minnesota, IIRC. Then two cheeseheads and me.
I was looking into getting free space in the community room of a bank in Oak Creek, south of Milwaukee near the airport. I could get the room on a Saturday afternoon and maybe on Sunday if needed, but I would have to leave it up to each attendee to find accommodations. It would be about 1.5 hours from Chicago, and about the same from Madison; about a half hour from my place.
But it seems that the Chicago dudes were working on something, so I'll sit tight for now.
