We use to do this when we were kids behind a snowmobile if you stopped too quickly you would slam into the back of the machine and if you punched it the person on the saucer would get a face full of snow
That's something that your kids will remember forever
Back in the 60s, neighbor would pull about 5 sleds with his car around the block. Cudoos to the generation that somehow survived childhood without a warning label mentality. “If it hurts, rub some snow on it”
