The Slimey Crud Run is on May 2, and starts at the Kit Korner Bar in Pine Bluff, Wisconsin. You take your own route to Leland, and then your own way back to Pine Bluff. There isn't an official start or end time. Supposedly there will be a lot of cool classic bikes to see. I've never done it myself. I think they do it again in October. I found out about it on the Madison sportbikes website, but you have to be a member to see the messages.
