Dj, you spoke of unstopable runners ! I've not hunted much outside ohio so I'm not sure if you experience this or not, we currently have snow and this is how I watched this happen. Yesterday my partner and I start into about 400 acres of clearcut thicket, heading for a particular spot in the thicket we we're gonna hunt the dogs into the wind. While setting upto make this run the wind was at our back going into a different thicket. From the ridge me and the dogs were on I watched a large hog bust outta a thicket on a dead run several hundred yds away! We had been silent setting up for that hunt and I'm sure that hog smelled us from atleast a cuple hundred yds and took to runnin I put the dogs on its track when we got over there and they followed for about 1200 yds. Never saw the hog again that hogs tracks were 10 and 12 yds apart for the entire 1200 yds , probably longer because that's where I stopped. Do your hogs act like that ?
If you are asking if some of our hog cut out when they wind us. Yes they do. I know that hogs have a very good sense of smell too because one time I was sitting in a blind about 12 ft off the ground and I was facing west and the wind was north to south. I had deer walk right up to the stand that I was in and never winded me, then a large hog walked out, taking the same track as the deer and he threw his head up, winded me and was gone. Way before he ever got within shooting range.

Hogs where we live are very skiddish.
