Dave,
....The game wardens here in SE Texas suggest building panel traps and bait them with vinegar. ......

Vinegar? Why vinegar? Do hogs like pickles??
Bill,
Hogs have a strong sense of smell. Hogs like things that are pungent, (rotten sack of onions), rank, and strong smelling...the nastier, the better. We used to soak corn in vinegar and add a little yeast to the mix and store in a shed until the top nearly blew off of the 5 gal bucket. The hogs sensitive sense of smell can pick up the smell of vinegar from quite a distance.
