I’ll never forget a moment from the bus trip I took across the U.S. west as a kid when we got to Montana. We had been driving for hours and got to our cabins far from everywhere late at night. A bus load of tired kids filed off, eyes half open, and then someone said “Hey, look up!”

Cue two dozen kids saying “oohs and ahhs” in sync. Don’t think I’ve seen such a spectacularly starry night since.
