They can get pretty bold at feeder time.
I was in a trap once about to set it when a handful of pigs showed up. I didn't dare open the trap, I got one of them before they scattered. It was somewhat of an ironic situation.
They were about 20 ft from me, the red one came in a little closer but spooked when an old boar fussed at me back in the cedars. I unsnapped my pistol about that time, he doesn't like me much. I think he knows I have plans for his future, I've got a broad-head with his name on it.
