For reasons that I am at a loss to explain, the water in the fountain at Philadelphia's famous Love Park (home of the "Love" sculpture on which the stamp and posters are based) has been a particularly bright and unpleasant shade of pink this week. I mean like neon pink. This has happened before, apparently - the picture linked above is from last fall sometime, though I don't remember that particular outbreak of pink.
The other day, my wife and I were walking toward the fountain along the Ben Franklin Parkway and one of Philly's huge army of insane homeless people was standing at the corner of the park, raving about something. As we drew closer, we realized that he was upset by the water.
"There is a crime being committed - this water is Pink," he yelled at us, then stormed off toward the Art Museum.
