If cameras (and especially real time cameras) didn't have any effect on when/where/how deer are harvested, why would P&Y block entries from real time cameras?
The answer is ecause that's ultimately the point of cameras. To "inventory" and pattern certain deer so as to try and increase the odds of seeing it and killing it.
If you don't think they are that helpful, why use them during the season? Why not just do your "inventory", form your "hit list" (I hate both of those terms) and then pull the cameras once the season starts? Why not just hunt using your "woodsmanship" skills and let the chips (or deer) fall where they may?
