Why Do You Think He Had The Crutches?

Tonight, we were driving on one of the major north/south arteries of the Big City. It has three lanes in each direction, with a concrete median most of the way. It was packed with cars and they clip along at a fevered pace. About half-way through one block, I noticed a person waiting on the median for a break in the traffic to jay-walk to the west side of this street. HE WAS ON CRUTCHES. Do ya think he's tried this before? Hmmm...slow learner, maybe?
