I finally nailed this boar last night with my crossbow; I never saw him during the day during deer season, but I would get plenty of game camera pics of him at night raiding the feeder. The problem was that he was one smart piggy, and no matter what nights I decided to wait up for him, he would never show up. Anyway, last night the temperature was dropping, the wind was howling out of the northeast, and I decided on a whim to go sit out in the blind one last time before I took it down for the season. About 3 hours after sundown sitting in the dark, I managed to see his outline wandering up to the feeder. I waited until he got broadside, then I let him have it with the crossbow. After hearing the thunk of broadhead hitting pigskin, he let out a loud squeal and took off into the darkness. While I was waiting for him to expire, a young sow happened along, and I shot her too. Unfortunately, when I went to go look for the boar, I thought he had gone east, when in fact he had turned north, so I didn't find him until this morning. Oh well, at least he won't be raiding my feeders any more.
Oh by the way, if you read this far and thought I was talking about a sow of the porcine variety...gotcha!
