Yep, walking to or from my stand in the dark will sometimes get me nervous.
We have copperheads (least of my concern), bears, coyotoes, and wild dogs (the biggest concern) Add to that the other hunters and the woods are a little dangerous.
As for having a weapon on you. Yeah, but, are you gonna be able to draw you bow back on a wild dog and shoot it while it is running full tilt at you?
I am not going to let those creeps decide where and how I hunt. I just tough them out. I understand that there is nothing in the woods at night that isn' t there in the day, but, atleast in the day I can see them!
One of my favorite stands is in the bottom of a valley where bears are seen every year. Also, there are several wild dogs in this area. The woods are thick and made of giant pine trees. When walking under these pines, even if there is a full moon, you can' t see a thing. The ground is quiet because it is all old pine needles.
I think alot of it is vulnerabillity. Humans are most vulnerable in the dark. We don' t have a good sense of smell, and our hearing isn' t that good either. We rely on our eyes, and when you take that away, we become a 3 legged cat surrounded by a pack of dogs
