DF,
You're right. They've wised up to the helicopters. Survivors will bed up in some thick cover and not budge.
The only way to put a dent in their numbers is too trap.
Hog doggin' with a knife is an adrenaline rush! NV over feeders or AG fields is the next best thing.
I've been along with the hog dog guys here in Louisiana. Seems to me they catch a few, but a lot get away. If you have large numbers, I don't think the dog method would make that big a dent.
And, knowing how smart those rascals are, I would think they'd wise up to the NV/feeder gig sooner or later.
Trapping may be the time tested solution, although they wise up to that, too. I guess methods have to be constantly upgraded. Snares seem to work if they get smart to other type traps.
