A boy and his wagon

We've been hitting up yard sales the past few weekends and while I was looking around at one, Tripp found this wagon and started walking away with it. And for a dollar I thought it was a pretty good deal. It keeps Tripp entertained for quite awhile. He likes to put his toys in it and pull them around. The only mistake we made was putting him in the wagon. Now we can't seem to get him out of it.
