For the end of July and the start of August I'm going to be in the Madison/Wisconsin Dells area visiting family.
I think I'll shoot for the Time Warner Cable Whitefish Bay Classic on the 29th.
Make sure it's not full. Superweek races tend to get that way. Especially on the weekends.
Failing that, you could do a Bombay ride in Madison on Sunday. Those are practically like races.
