I drove by the rink the next day and the unit was sitting outside slightly black on the back side of it! The Olympia is built on a Chevy pickup, while the Zamboni is its own frame and design. I had a 68' Zamboni for my backyard ice rink, sold it about 12 years ago. We just don't get the cold winters like before, and the kids are gone, so no need for it anymore.
