RE: in the dark
I've never spent the night, but I don't think it would bother me... once I am IN my stand, I have no fear, I am very relaxed actually!
I don't know of anyone that spends the night in their stand, although I know many who get out there really early in the morning and then take a little nap before shooting time, my BF did that once and fell right outta the tree!! Sheesh! (yes he had a harness on)
