I used to live there and sled there as a kid, but haven't been back in many years, but I know the fella you should see, go stop in at Thornhill Motors, Subaru/ Mazda dealer there. You'll want to talk to Brent DeJong he owns/runs the place, he's an old friend that I sledded with as kids and he's still big into it up there. Knows the area well as he's lived there his whole life.
