The other night after dinner I let Carter ride around the block on his bike. I originally was just going to take a little loop around our block, but decided to take the mile and a half loop around the neighborhood. We got back to our house and Carter wanted to go more, so we went about another half of a mile,, I thought that was a pretty impressive bike ride for a 3 year old! The whole time we were riding Carter kept saying, "I'm exercising."By time we got back home the dogs were much more tired than Carter was! Funny guy!
