Yeah, you can still hunt them but from what I've been told the are pretty hard to find. I talked to a guy form MB con that did the big game aerial counts and he says they stay in some pretty thick crap. The Mars Sandhills area near Libau and Libau marsh area have a few left. He said there aren't as many as there used to be and they stay pretty nocturnal. But he has seena few "Hawgs" from the air
If you go to the MB con website and look around you can find a map that shows areas of sightings and relative density of the sightings. But it's pretty old.
