Central Park / New York, New York
A sign of the pending Fall season - leaves on the sidewalk. And for whatever reason, Ginkgoes are usually one of the first to start dropping their foliage. Fossils recognizably related to modern Ginkgoes date back some 270 million years ago. But advancing to more modern times, they have become very popular as an urban street tree. I suspect because of their hardy nature and upright form. You can spot them all over the city by their distinctive fan-like leaf shape.
