UNDER THE HIGHWAY IN SOUTH PHILLY down by the Navy Base, and across the street from where the Phillies, Flyers, Eagles,Sixers, Phantoms, Wings, Kixx and Soul play, skateboards rule. The city's official skateboard park on the south end of F.D.R. Park has been attracting skaterboys, stunt-bikers and in-line skaters to its ramps and jumps ever since the city closed LOVE Park to extreme sport enthusiasts. I captured the image of this young man in mid air on Saturday. A friend who saw this photo thought it would look great as an updated statue atop City Hall representing modern Philadelphia.
