I do not know about the rest of you but I am usually too darn excited when I am headed out to me treestand spots early in the morning to be afraid of anything. I can just feel the adrenaline pulsing through every inch of my body and that rush of confidence knowing that I am going to get my deer in only a few hours...
...ofcourse, by the time 9 am rolls around and I do not have my deer then the adrenaline wears off....but it is light by then...
I carry a flashlight whenever I walk in the dark. Can' t be too safe where I hunt though I do tend to get there hours before the regular yahoos.
