None in my situation. My honeyhole is behind our house in the woods but I like to do the same in other spots. I try to get there a minimum an hour before shooting light. I don't fall asleep easily so I just sit back and listen for sounds. Kind of relaxing. Plus, my 2 cents is if you do bump something in the dark, better than in daylight when they see you for certain. And I've had deer circle back to check out the situation when its just light enough on the few occassions I did bump.
