Galen has started pulling a sled! He started training to cart in the spring of 2009 when he was a baby, started pulling a cart summer 2010, and I just tried hooking him up to a sled on Tuesday! He is doing so well. I can drive him in the cart, but I'm not sure about the sled yet, so for now I am just leading him. Got some pics but I will have post them later. I am in love with this wether!
