I went on a fenced hog hunt about 10 years ago. I think it was a couple thousand acres in Tennessee. I went with a group of about 10 people and actually, I did not hunt, but went along to take pictures.

The pluses:
Great comraderie, great food, lodge owners were great hosts. Hunted with dogs and I just love watching trained hunting dogs work no matter what type of hunting. The dogs were great because they were really well socialized too. That makes it all the better. We walked A LOT and got lots of exercise. The first day we worked hard, but never got a shot. The second day, three people in my small group were able to take a boar.

The minuses:
Even though we and the dogs walked A LOT and put forth a lot of physical effort, when it was all said and done, every kill that I saw was in visible range of the fence. Basically, the dogs chased until they were able to stop some hogs near the fence. I did not like that.

I definitely had a good time and would not fault anyone who wanted to do that kind of hunting, but it is definitely not something I would do again. I'm glad I went though so I could see what it was like first hand and not just from hearing about it. High fence hunting is not for me.
