I think our Indian summer is over

Tomorrow's the last day of +75 degree weather, then it's back to reality. There are 6 black walnut trees in a 500 square foot radius and the yard is just covered with squirrels. If you ever try to crack a black walnut wear your rubber gloves and carry a vise and ball-peen hammer.
If that doesn't stop you from getting to the nut, the juglone might.
'It is sometimes used as a herbicide, as a dye for cloth and inks, and as a coloring agent for foods and cosmetics.'
I'm still trying to get the stain out of my fingers after 2 years.
