If I were you I would contact Pine Hill and explain you are coming from Sweden to hunt birds. I suspect they will find a way to accomadate you. You can also Google quail hunting in SC and again for GA and you will find many other places to hunt quail, bit not all use the mule drawn wagon of horseback. You ask for other species to hunt. Both SC and GA have a lot of hunting for wild boar, here are two places I have hunted wild boar.
