I have never personally ever been "treed" by a raging hog, but have had some close encounters with Javelina and know people who were new to hog hunting and inexpeirenced who had been chased up a tree by a wild pack of hogs. I also have heard stories of some of my old school buddies that lived out in the boon docks who would get terrorized by groups of wild pigs at night fighting with their dogs and other pets.
