Today's photo word: Moving

I've been wanting to get this picture for a while or at least one like it. The problem was that most freeway overpasses have grills between the bars which really get in the way of a clear shot. I can see why they are there. There are some sick or careless people who have nothing to do but toss things down on cars on the freeway. I was thinking of taking the shot at a busy intersection but I wanted a vantage point above the traffic.
Anyway, today's word came from Traci.
