Funny, it reminds me of what happened to me two years ago. I was collecting morels in the burns here in montana and I saw this guy a few hundred feet from me and I motion to him indicateing this is my spot and the guy just kept comeing towards me ignoreing my motions. Funny thing about this guy is I could see his body and he just wasn' t moveing right, kinda like backwards/awkward and he was ugly as hell, maybe kinda scarey. As he got closer I could see he had a plastic halloween mask on the back part of his head, and I said to myself, " I got to cheque this out," so I worked my way up to this guy and after a while we started talking and I had to ask, " hey whats with the mask?" He replied that his brother was attacked the previous year in Idaho by a cat from the rear and the mask is suppose to give the impression that it can see it and thwort out an attack. To each there own I guess.
It enters my mind of an attack at times but then again so do the Griz and Blackies with cubs and along with the elk/moose calving, but if you spend so much time worring about an attack its very difficult to enjoy a hunt. Good Luck, Bobby
