I was deer hunting with a buddy of mine right after the "fall back" time change. He was annoyed that we would probably not see any deer for a week or so. Because they were moving 30 minutes before dark the week before, he said they were probably moving 30 minutes after dark now and it might take them a week to adjust. Since they were moving about 7:00 or so the week before and now it was getting dark at 6:30. I just stared at him for a few seconds. Then I told him I did not think the deer had watches.
