This is what a loaded walnut tree looks like.
Each walnut is 3-4" in diameter. They are hard as rocks. Hard enough so when you have children, you spend the first 13 years of their lives randomly yelling: "*DO*NOT*THROW*THE*WALNUTS*AT*EACH*OTHER*."
But then comes fall, in more ways than one, since there is no Mother Walnut to tell the tree itself Not To Throw The Walnuts.
And the only way to pick the walnuts up, is to stand under the tree.
