I don't know if the north central division has ever had a rally in Black River Falls, WI, but if not, youall might consider the NCN campground there. NCN stands for No Clothes Necessary, and it could be a lot of fun. Plus, there are some good riding roads in the driftless area of Wisconsin. The pre- and post-Sturgis rallies there are pretty wild, but non-Harley riders are not too welcome.
