Lee,
I also hunt in South Carolina...few thousand acres across from Groton Plantation...directly on the Savannah River....the river is up real high now..hogs are on the hill...and so are the gators. I am going this weekend...they're telling me that they've never seen gators as thick as this in 30 years ...10 and 12 footers are everywhere...naturally that is pushing the pigs out to higher drier ground..and we should have a great trip...my partner and I have taken 60+ hogs in the last couple yrs, the largest being 467 lbs...and I can tell you that was NO PEN RAISED HOG...right now I am hunting a couple boars that will be legitimately 300+...and none of these hogs are anything but rooters well removed by generations from a pen- there has never been a hog in a pen on this land. Yes,maybe some of he neighboring properties have done so...and you are right, there are lots of places where a 200 lb pig is a big one..but I certainly believe that major river drainages will grow on average bigger hogs, just as they grow bigger whitetails.And you are right, what makes hogs angry isn't people ( unless you get between a sow and her baby) it's the dogs.. I hunt them on the ground, stalking, with a recurve or longbow...and its just about the most fun you can have with your britches on. And boy, do they taste good! We soak the cuts of meat in apple juice for 36 hours, than put it on a big grill (beside, not over the fire) and smoke it for about 15 hours....pull it apart and eat it,or the lesser cuts get chopped up, and add BBQ sauce to make sandwiches- I'm getting hungry just thinking about it!
