Cool, I know alot of people that still run the old timers.
As a matter of fact: Lake Park, Minnesota (between Moorhead and Detroit Lakes) has a meet called The Old Timers Run that should be comming up real soon. The local club has been holding that show for many years. I don't know all of the details, but my Wife's dad goes every year. It may be a trailered show this year though. I went last year, it was alot of fun. In the morning they hold a show with catagorised entries then in the afternoon there are thousands of antique sleds running the local trail systems.
