This showed up along the bike path the other day. From across the street, it merely looked really really dirty.
On closer inspection it looked like it had spend time not only in a damp place, but actually underwater.
The drive train- YIKES!
It even looked like coral was growing on it, although that seems impossible. Perhaps it was fragments of sponge rubber, like a mattress pad?
I wonder how it came to be in such shape, and how it came to be propped up against a trashcan on Memorial Drive?
