Three days ago I was enjoying the fresh air while out for some exercise by alternate walk/jogging for about five miles.  The breeze made the jog pleasant and I was feeling pretty good about being outdoors.  I live in a neighborhood that has bridges over the Intracoastal Waterway.  These bridges are manned by attendants who have the pedestrian's best interests at heart by making sure we stay behind the barriers when the bridge is raised and lowered.  They also have a prescribed way of making sure traffic is clear before they raise the bridge.  As I approached the bridge on the farther part of my route, the bridge was lowered, the arms went up and I started across the grating.  My attention was immediately riveted on the brige tender who was bleeding profusely from his arm and I couldn't tell if his leg was also bleeding or just catching the blood dripping from the gentleman's arm.  As I got closer a lady was quite excited about the whole event.  She said the bridge tender had tried to stop a car from crossing the bridge and the driver of the car hit him with the car and kept going.  She said the bridge tender was taking blood thinners, he was bleeding profusely from large gaping wounds that were already starting to swell.  The whole situation looked quite painful.  The paramedics arrived and I went on my way pondering who I felt more concern for - the bridge tender, or the anonymous driver who just drove away.
