I have found:
- a wrench that I still have in my tool box, forget what size it is.
-A lot of dead animals
- old tires
-a lot of fast food garbage
-cans & bottles

The most interesting thing I found was in the middle of the road. It was a 6' bull snake basking in the hot summer sun. I picked it up & moved it to the shoulder, still in the sun. I did this because I figured if this animal survived to grow this large it deserved to live & not be hit by a car. It didn't seem to mind me picking it up & moving, it seemed like to know what I was doing to help it. On the return trip it was gone. I figured it crawled away after soaking up the heat it needed.
