There are many versions of "deer drives". At our camp the watchers were all on marked spots and knew where their neighbor was. About a half mile away one or two men with dogs would enter the bush and try and put the dogs on a fresh track, at which point their job was over ....Each stand was chosen according to established game trails and in almost all cases were in open hardwood. If we had a watch in the green stuff, then it would go to an older guy with a shotgun...who we could count on to stay cool when he heard a noise. The doggers themselves realized that they should stay out in the hardwood as they approached the line of men as well.
In over 25 years I don't recall any close calls, but a few people were invited to leave because they went for a walk away from their assigned spot.
i feel than needing to see horns has slowed down a lot of quick shooters.....
