There is also a fine line. What if you have 10,000 acres, and it is low fence, but you manage it only for deer? Thousands of acres of food plots and/or feeders, and you are making mineral licks, etc.. Yes, the deer can come and go, but plenty of giant deer will be living on the property their entire lives just because of its size and how you are manipulating the land. Is that "real" hunting?
There is a grey area. Some "hunting" is easier than other kinds. If you want to, you can try to kill a deer using a self-made stone hatchet, sitting in an area of dense woods with no food and no trails. Then you can say people who hunt over fields with those new-fangled recurve bows are not "real" hunting.
