I've driven by the Edgar Allan Poe Historic Site in North Philadelphia dozens of times over the years when the trees around the Raven sculpture were in full bloom. It happened again this morning, and just like every other time, I pulled over, looked at the blossoms, and decided the light wasn't right and there were no visitors around, and little chance any would appear if I tried to make a picture. Three assignments later, I was driving back to the office when I passed the small park on the Ben Franklin Parkway at 16th Street. Similar blossoms, but this time the light was good, and there were people all around. So this time I got out of the car.
