We used to have a single Cyl. AMF Skidaddler when I was a lad. I know it did over 30 MPH on flat ground. It was pretty cool with orange body, black seat and blacked out hood with orange and yellow flames running up the front.
We used it to haul wood. Dad would cut, my sister and I would load up the homemade sled and pull it back to the truck. When the truck was full, dad would haul the wood back to the house and unload while my sister and I ran that snow machine around the property. Then he'd come back and pick us and the snowmobile up.
Yeah. Not like modern sledding.
