It is autumn and I have three black walnut trees in my yard (and just to mention a tin roof on my house). The squirrels run around this time of year as if they were pepped up on squirrel nip and maybe that is what is in those black walnuts; I don’t know, the damn things are too hard for us humans to crack! I came home yesterday to a large hole in the pot of my basil. Why? Tell me why?
