Poser,
You have never had any luck walking up on hogs before? Where I used to hunt in Mississippi, I regularly walked within shotgun range of them as long as I had the wind in my favor.
I was scouting ducks once, and I walked along a large tree that had been blown down. When I rounded the end of the tree, I walked up on a group of sows. There was one really large sow, two to three in the fifty pound class, and then a mess of piglets. The crazy thing was the piglets were huddled together in the base of a big cypress tree while the sows were rooting around. For the few minutes I stood there, I could have hit any of them with a rock, until they got wind of me and left.
