There are a lot of different leaves in our yard, after all we are in the woods. Being extremely dumb, it took me a while to realize the ones I was drawing were coming from the same tree. Then I noticed what looked like hard tennis balls lying around the yard. I searched the inter web to see if I could identify what kind of tree it was. I discovered it’s a black walnut tree.. The walnuts are inside the tennis ball looking fruit. I feel a little smarter this morning.
