Jumping in here too. I have a hunt set up the 11th/12th at Hog Heaven Ranch in Muse, (northwest of Labelle, a bit) and near the Cecil Webb Mgmt area. This will be my first, however the group I'm going with it will be their seventh trip they like it so much.
You can select a blind, tree stand, or stalk. If you want a guaranteed kill, they will give you one of those. Prices are reasonable.
Like you, I would really like to be able to go out on property and attempt to eliminate the hog infestation, but as others have said, owners are afraid of lawsuits, property being abused, and their own animals being killed by irresponsible (hunters?).
As far as the snake hunts, I think you'd have to be with someone that knows the glades pretty well to get off the beaten path. Saying that, a few years back before the problem was announced, I was on a dirt road in the glades about 6 miles off US41 and saw a pretty good size snake cross the road maybe 200-300 yards ahead. By time I reached that point it was gone into heavy brush and along the canal. By the mark left in the dirt on the road it looked to be about 3-4 inches in diameter.
If you find a place to hunt and want company, PM me and I'll do likewise.
