Yeah, I could understand it on public land for safety from other hunters. And for the places where bears, bores, and snakes could mess up your morning walk. We have bears and mountain lions, and bobcats around but hogs are not a problem in this part of Missouri, and it's way too cold to worry about snakes during deer season. I built a new wood platform in a tree one time and had a guy walk in with a light opening morning and try to climb into the stand that I had built. He left when he saw me, but it was no trouble. If he had got there first there would have been plenty, as he would be climbing down or be dragged down! That's another thing that I don't have to worry about on my property, like a person would on public property. On private land, you better have permission to be there or be ready to be arrested and fined.
There do seem to be many good reasons for using a light, but I will not be doing so.
