khardrunner, this winter would be a great time for your dad to scout out the Francis Marion NF, it is a pretty neat place. About a 2 hr drive from Columbia. Lots of gravel and dirt roads to drive, and plenty of gated NF roads/trails that are perfect to scout with a bike. Very flat of course, since it is near the coast. The guys I knew who had the best success with killing hogs and deer there used small jon boats to hunt the creeks and inlets off the Santee river. Good turkey hunting there too, so the spring turkey season would be a good time to scout/hunt the hogs as well. Several NF campgrounds there, so with this much time to plan, you could have a relatively low cost/high quality hog hunt.
