I don't hunt Deer much anymore, Deer are dumb, the challenge just isn't there. Hogs can be smart and a lot harder to hunt.
Especially if they get older, over 3 years or so. A six-seven year old Hog is a smart Hog and much less likely to make many mistakes that will get themselves killed. They can be way canny and are smarter than most hunters.
Me and a buddy once shot 21 Deer in three days, on a contract from the County. They built a road right through the middle of a bedding area, a feeding area and a mineral patch. They decided after three people died, the Deer had to go. I guess they never heard of the six "P's" prior, planing, prevents, pizz, poor, performance. They actually built that road through a swamp and have had to redo it every two years since.
Maybe it is time to forget the Deer and hunt Hogs.
Pretty much the same reason I like to Hunt Fox, they can be smart and hard to hunt, challenging. One farmer had a couple of hundred Ducks, a Fox was slowly killing them off. I lent him a shotgun and I spent many hours trying to bag that Fox. The closest I ever came was driving home from a bar one night and that sucker ran across the road. Fox two hundred, farmer and hunter zero. You have to respect something that canny.
