I'm sure there is the sport aspect for some. The food aspect for others.
My experience with barrs.... I have cut countless boars. I have caught ONE barr. He was so far back in the woods that I only took out the head. Would have liked to make sausage, but this one was quite large (est. 275-300#), and too deep in the woods for buggies. He whipped a couple of dogs too. Having only caught that one barr, I can't really make any bold statements about how barr hogs act regarding running, baying, fighting...
I will say this though. As a person who has competed in plenty of contests. I want to compete against the best dogs, best hogs, and best hog hunters. Barrs, feedlots, etc. It doesn't matter, because there will never be a level playing field, this isn't barrel racing.... It's hog dogging.
Who really wants to win a contest when the best aren't even competing?
I like!
