Apparently the Corps of Engineers will allow hunting in the Somerville Lake Reservoir area (Lee County, Washington County) for free as long as you have valid hunter's education/license and apply for the permit. Can only use bow, shotgun, dogs, and livetrapping.
I grew up in Lee County and can absolutely confirm that the feral hog population there is insane.
One night spot-lighting near Somerville Lake we stirred up hundreds (no hyperbole) of hogs eating out of cattle range feeders.
If you wait till a full moon with good ambient light (or bring your PVS-14) you can go without spot-light and really murder the bastards.
Firing a suppressed 300 BLK dropping hogs while their buddies are looking around confused can be quite entertaining.
