Joe...all the stories about aggressive hogs tend to be a little over the top...most of the time. If you have one in a trap they do feel cornered and are certainly willing to fight, as most wild animals would, but I don't worry about one attacking me in the woods. They usually know you are there long before you see them and they are headed away as fast as possible.
The hogs are good eating and fun to hunt. I hunt deer every year successfully, and usually shoot at least several....but if I were to give it up and just hunt hogs I would be just as happy.
I have a pretty large boar on a camera today, and will be going out in a couple hrs. again to see if I can locate him.
