What about pigs? Not the little javelinas of the Southwest (although they can be nasty enough,) but the big Russian boar/domestic pig crossbreeds?
300-450 lbs of pig w/3" razor sharp tusks coming at you through the thick bush found in southern swamps can get the adrenaline pumping almost as much as some of the other game mentioned.
Shoot straight, stay safe, and have a blessed day.
