The point of the fence is you don't want people leeching off of your hard work. Loosing animals can be very expensive. On many of the larger preserves most animals would never leave the preserve because they have all the resources they require right there. Tecomate ranch is a prime example of that concept. He has no fences yet the animals stay. Many of the hunts outside the fence that are guided also run close to 100% so there is not a difference in success rate. The only difference is your mentalality of it all. The the average homerange of a whitetail deer is rougly 200 acres. So if a preserve is larger then that the deer is affected very little by the fact that there is a fence. It does not change its ability to escape from hunters. Most deer run a couple of hundred yards from the source and circle back around to end up very close to where they started. The reason the success rates are so high is the fact the people guiding the hunts are experiences and familiar with the terrain and habits of the animals on it. Its not because the animals can't get away from the hunters. Hell you can hunt deer in some areas on 10 acres and have deer avoid you.

You obviously have a deep rooted problem with preserves. Which again you need to be respectful of other hunters just as they need to respect you. Just because you don't want to hunt on a preserve because you don't think it would provide you the hunting experience that you would enjoy doesn't make it wrong. And it also doesn't make the people who do hunt there not hunters. You can not fairly judge something like this that you have not done yourself.
