Florida has one of the largest wildlife management areas programs in the country- almost 6,000,000 acres. Some is owned by the state and some is managed by the state. Florida also has 21 million people and a lot are hunters. The Florida Fish and Wildlife commission has to manage the WMAs and also make sure animal populations are healthy. Thousands of hunting permits for those lands are issued each year. Obviously, it can't be a free for all, or then the wildlife wouldn't be properly managed. Those lands also see a lot of use from non hunters. Especially in the winter, when it's actually nice enough to go outdoors and do stuff. There is also plenty of private land, and acreage is still pretty cheap in the interior of the state. I know a lot of guys who own interests in land, or lease hunting lands.
I'm not anti hunting. I understand how it works. My own land is open to hunters, and I've seen a couple of deer stands on it, but I have no idea who they belong to. I don't mind at all.
