Imagine yourself on the flank of a mountain, at a high altitude. It's nighttime and so dark that you can hardly see where you are. You've got to set up camp ... but under no circumstance are you allowed to use light of any kind. Not an easy task!
I found myself in this situation. It was part of a military exercise. After struggling for a long time in the dark, we managed to set up our tents. It was difficult to find a good spot for them, because the terrain was rocky and full of bumps. Also, we couldn't find some of the equipment we had taken out of our backpacks.
A few hours later, a full moon rose over a ridge. The whole side of the mountain was in full light. We then realized how much better our camp would have been set up if we had been able to see what we were doing. There were actually plenty of flat grassy spots for our tents, but we'd set up most of them beside the grassy spots on rocky ground. And the gear we had been searching for was just by our tents. A little light would have made life a lot easier. It would have shown us that all we needed was in fact there.
