I do a lot of hiking and exploring into some really rank, nasty areas where very few people would have any reason to go. These are the places where I believe you have to go to see things unknown. I came across some wild citrus fruit growing on tall trees. At the bottom of these trees were peeled tangerines. The fruit had been eaten. You have to have hands to open citrus fruit.
The peels I found below the tree
You can see how all this was found in the video below. My understanding is you must have hands to peel this fruit.
