When I lived closer to my hunting spots, I would shoot for an hour before shooting light. However, now, with one and a half hours from pulling out of the driveway to sitting in my stand, I get there a little later.
I, also, have learned to not get rattled about being late. I just stop for a while a little ways from the car to collect my thoughts, then still hunt to the stand.
Now-a-days, I take a lot longer to walk in, even in the dark. So, I end up getting settled closer to sun up than before, but I see more deer because I am more careful and spend more time listening on the way in than when I was younger.
