Lot's more than just feral hogs to worry about
I hiked a lot, primarily in AZ, NM and Texas, and mostly during daylight. I seldom run across a feral hog, as compared to deer, snakes, lizards, turtles and bears. The largest numbers are coyotes and signs of cats.
While I'm sure you could find a place where it's mostly wild hogs, I'd bet the primary threat to most hikers comes from coyotes, cats, bears and snakes.
