Although this guy was walking I've seen many sleds like this being pulled by skiers. The main idea, of course, is to be able to bring your small children along in a safe, comfortable sled. Here's my personal web page about skiing: http://www.rogerwendell.com/skiing.html 02-28-2009
Baby has been bored pulling her tire. I finished building a wood sled so Meg came to the farm to hook her up and drive her. Meg is an experienced teamster and this type of training SHOULD NEVER be attempted by an amateur like me! Baby was a little squirrely for 5-10 minutes and then settled into pulling the weight. Meg said she was impressed.
