We wrestle them... Ive been face to face with a good bit when they are alive and well, also the people I do it with have been wrestling them since they were 8 and they are now in their 30's We have only been charged once. We bayed a sow with her pigglets. other than that all the get is boars chomping/sharpening their teeth when you hog tie them.
A lot of boars mistake you for trees when you have camo on. Their eyesight is poor and they run towards you and dart the other way thinking your a tree.
We stalk them with bows a lot to. Just stay behind trees and they wont get you. Also make sure you give them time to bleed out after the shot.

If not there is always treestands.
