Model A Snowmobile

We were driving by a farm and saw an old Model a snowmobile streaking through the snow, towing a small red sleigh. I had to look twice, to try and determine what it was. I turned around and drove into the parking lot of the farm. There was a gathering of about a dozen Model A and Model T snowmobiles! I had never seen one of these before. They are really interesting.
What a great event!
