I've only found one hole in the fence. The neigboring land owner makes sure that the fence is in good shape because he charges to hunt his property and buys pigs to stock his land. The one hole that I found has a trail that leads to two feeders that I hunt over. I've taken my last two pigs from there. There is a deer blind set-up 100 & 125 yds respectively from the two feeders.
The trail goes through the fence, past both feeders, through some brush, past a third feeder in a bottom (fenced in to keep pigs out), into a huge wallow, and then into the brush. I'm going to try a set-up by the wallow as well.
During deer season, these blinds are used for deer hunting. So, I'll use the stand with my new feeder that I'll set-up next week for the Thanksgiving trip and these other blinds this week.
I agree with the quite Boar theory. I always hear the sows before they arrive. The big Boars just slip-in and surprise you. There's nothing like seeing that huge shadowy figure come slinking into your sight path before the sun comes up and you can barely see.
