Here's something I found a few years ago up in the Bronx. This was at the foot of a dead-end street near Baychester Avenue just off the Post Road. I was still driving around the Bronx for the real estate job then, and I was on this street to photograph a nearby house. As I was turning the car around at the end of the block, where the subway cut through, I spotted the tire at the base of the tree.
Looking again I realized it wasn't just at the base of the tree, it was around the trunk of the tree, completely encircling, like an Elizabethan collar, the trunk of what had to be a twenty-five foot tall maple. A tree this size would have been growing here for at least fifteen to twenty-five years, with the tire around it for most of the time. Or at least since the branches spread far enough and the trunk soared too high for anyone to drop a tire on from above.
Have a closer look. I've been there several times over the years, and have pictures from all sides, in all seasons. This is for real, no Photoshop tricks.
