Francis Marion State Forest is loaded with them. I've been hunting them up around the Jocassee Gorges in Pickens County. I've seen a couple of real monsters up there. The last three times I've been I've seen 20 hogs. I wasn't able to seal the deal with my bow on one there, yet, but I'm confident I will soon. The mast crop has been so thick, the hogs aren't sticking to one spot.
There are some designated hog hunts in several different areas that will allow you to use your bow after deer season ends. On public land, though, you're limited to using the weapons allowed for whatever season is in. So, being able to use a bow or centerfire rifle will end Jan. 1 on the WMUs. On private land you can use whatever you want, whenever you want on hogs.
Where do you duck hunt?
