One summer at least a decade ago, my daughter and I were driving across North Dakota at night. If you've never been there, it's pretty much a big mostly vacant prairie, so light pollution is not much of a issue.
Mini-me and I were chattering about nothing in particular as we drove; out of the corner of my eye I caught a flash of light. I pulled over off the highway and told her to come join me.
We lay on the hood of my car for almost 45 minutes watching the Northern Lights play across the sky, not talking, just watching the lights flash and dance over the horizon, shot through with faint greens, blues, and every now and then, reds. We were completely alone the entire time, no one even passed on the road. It was beautiful.
One of my favorite girl-child memories.
