Friday thru Sunday at the Convention Center. This show is usually fun and a good way to break your cabin fever. KTM, Husky, and BMW appear to be no-shows as usual but there will be more than enough entertainment from other vendors to fill a few hours of your time.

I think that the manufacturers that do not show are making a major mistake. The loyal riders and buyers do attend. The more there is to see the more will show. Btw this is a great winter for ice riding in sw mn on the rivers.
