From what I have read about bears. Is that they have terrible eye sight. So he might have mistaken us for chow. But I dont know I have read that and been told thats why. There smell and hearing are tremendous. Better then any other animal out there. The wind was working for us on this one. Been hunting these two bears for 2 years now. There is one there about 350-400 lbs I will bag him this year. Later
