Have you ever went hunting with someone who just couldn't seem to see game animals ? I use to go hunting w/a good friend once in a while who couldn't see a deer standing right in front of him. We were sitting in a big shooting stand on a powerline one day back in mississippi and there were six deer scattered out within 200yds -he couldn't see any of them. He thought i was acting a fool and horsing around -saying there were deer --RIGHT THERE ---. Finally he spotted a doe at about 90-100 yds and immediately got ready to shoot ,i told him to wait there's a nice six point buck right there. Well couldn't see it and then lost track of the doe he wanted to take . I was completely baffled but could tell he was getting irritated because he couldn't see them. Finally after a good 4-5 minutes he spotted another doe flicking its tail and nailed her w/a 7mm mag. The doe was like his second or third deer -so he was happy and i was to. Anyway i've been around other folks that you could not even point out a game animal to and have just thought it was odd they couldn't see them.
