Okay, I have a tree in my yard dropping these things all over the side yard, and I have no idea what it is.
It’s feels pretty solid and it about an inch and a half in diameter. I don’t know much about trees, so I could not tell you much about it except that it has narrow oval like leaves.
If you know what it is, please post here. I would really like to know, and Google image search did not seem to return anything that looked like it.
