There's a smaller swap in West Bend, WI in late winter about a month later after the Madison show. It's part of a automotive swap but has its own building it's housed in.

Then there's another at UWM in Milwaukee in December. Another in Oshkosh WI held at the fairgrounds at the end of March.

There's also the Iola Swap meet in Iola WI during the hottest days of summer normally which is a automotive swap meet but some bike stuff turns up there. But sweet lord get your walking shoes on, sunscreen on because this place is big and not much there for hiding from the sun. Plus it's Wisconsin so it's a humid hot.
