Seriously ... When you're hunting from a tree stand, how do you keep the squirrels from dropping nuts on your head? I hunted from a tree stand for exactly one (muzzle loading) deer season, when I lived in Missouri. DaRn squirrel(s) dropped no less than 40 nuts an hour on me.
They imported the nuts, I think. Acorns, Walnuts, and Pecans were the most common to hit. I think I was in a maple tree.
