Walk away and be the bigger man. I know its easy to say but if this escalates into something bad how will you feel later? Leave the bugger alone to gloat in his excrement. Ask yourself if it is really worth it. Do you want your kids to learn how to be an adult or act like a testosterone filled teenager? Who cares? Just walk away. You sound like a reasonablle man. Stay that way and smile. Tit for tat is for children. An eye for an eye is for hill billies and countries that are at war all the time. You will enjoy a peacefull hunt. After all isn't that why you started bow hunting?
