The light pollution from Vegas is wild. My buddy and I were heading towards Las Vegas from Boise on 15 about 20 years ago and, at around 2:00 am, I thought I was hallucinating because it appeared that the sun was rising. It took us a few seconds to realize it was the lights of Vegas… because we were still nearly 70 miles away.
I think this will be the only bit I remember:
[Fifteen-year-old] Landon thought for a second and nodded. “I do think the Sphere is cool,” he said, looking me in the eye. “But it means more light pollution. I’m trying to see the stars.”
