Same old invasive species stories. At Clarksville this last weekend we were covered up with pig sign but two of us hunting four multi-hour hunts each didn't see a live pig. We also did a couple of nighttime sweeps with night-vision gear at one of the big fields: no pigs. Hunting will probably be too labor intensive. Have to turn loose pigs infected with some pig-specific virus perhaps.
Would be nice to be able to send up small drones with thermal imaging capability that would beam back to your laptop. Find out which stands have the animals close. Locate the pigs during the daytime. Pretty hard to regulate pigs with shooting these days, same with the pythons in the everglades, though loosing restrictions, letting the fishermen carry shotguns and giving a bounty for dead snakes and pigs would be a good idea, IMHO.
