Sorry Jason, I'm not very knowledgeable when it comes to sleds, saw a few polararis, ski Doo, artic cat, names I recognize, but a few I've never heard of. I'm more a car guy, and they had a barn full of cars I've never heard of. If you want to see it all, it takes about 6 hours to walk through it all. Harold passed in 94 I think, and there was talk of shutting it down. They also had racks of early outboards, aircraft engines, and lots of farm gear. It is an amazing collection inspired by one person.
