A couple of years ago I spotted a big porcupine ambling through the woods towards my stand as I sat overlooking a bear bait. He got right below my tree, but chose the one right next to it and began climbing up. He went way up and began breaking branches off to get the acorns(?) to the ground. I kept a close eye on him when I noticed that up "there" he could have gone from tree to tree. Of course, I figured I was well armed if he'd gotten too close, having my BLR/.450 in my hands....lol.
