I went on a Pig Gig last year and am going again this year. Nothing is guaranteed, but the boys look after you. They did the work of finding a decent property to hunt, contacted and made arrangements etc. You just show up and hunt.
You meet some fine folks, get to rub noses with them brothers, and have a great excuse for carrying your bow instead of your briefcase for the week. Can't get much better than that.
Hint. . if you want them to hang around your camp, make extra desserts each night.
