Too many lefties building their unnatural nature trails out in the woods makes for some testy nut lovers.
Years ago, when I was a log-cutter, the little bastards would throw pine/fir/spruce cones at me -- the hard, little solid ones that hadn't splayed open yet. They would just rain them down on me. It was kinda cute, but it made me glad I was wearing a hardhat. I felt kinda guilty, cutting down their homes; but I got over it :)
Here's an interesting site. But you have to see it during the daylight hours.
