just got a call today from Michigan snowmobile association and they are having a groomer workshop at the kewadin casino in sault ste marie Michigan march 6 and 7. if you bring your antique snowcat and display it they supposedly let you drive all the latest and greatest in groomers. all you have to do is call Karin at 616-361-5861 and register. I think I may go......sounds like fun .......maybe a little gambling too. just thought I would let everyone know.
