I've had to revert to Plan B a few times over the years. When I read hiking forums, I often read about aborted hikes due to weather issues. People prudently will stop before a pass to avoid going over it in a storm and then end up behind their required pace. But several years ago, in Colorado, I started thinking in terms of a day being 24 hours and not restricting myself to conventional hiking hours. So if I had to stop in the early afternoon, my mileage goals were not necessarily blown since I was willing to hike in the evening hours or start very early the next morning. ?I think that fewer hikes would be aborted due to weather that causes perceived time limitations if hikers were more open to night hiking. Actually, after doing some of it out of necessity, I actually grew to appreciate the unique aspects of walking at night, especially under a relatively full moon -- it's a great experience overall to be out under the moon and stars walking (with a good headlamp, of course).
