From the looks of it, the tree area behind our apartment and beside the river used to be a landfill. Or, more specifically, a garbage dump for shoes. There are seriously hundreds of shoes sticking out of the dirt and muck. They'll all old, broken, and (at least to me) interesting. A while back I decided to take some pictures of a few of my favorites.
To me, the blue-heeled shoe looks like it's really something that died. Notice the blue tongue protruding from it's "mouth".
That's about it.
