For the eclipse in 2017, Mrs. Winslow and I road-tripped to a city along its path, and took up a post on top of a public parking deck. We'd done our homework on the event, and had our bearings as to which way to point ourselves when the time came.
As we were waiting for the event, a slightly younger guy came wandering up the deck. He would look at his phone, then look at the sky, then at his phone, then at the sky, etc. After a few minutes of wandering around like this, he noticed we didn't seem as puzzled as he was, and wandered over in our direction.
"You guys here for the eclipse?"" he asked.
"Yep, just waiting for it," I replied.
"Cool..." he said. Then after a moment, showing me his phone's screen, he continued: "I've got an app that can tell me where the Sun will be."
I took my compass out of my shirt pocket, and said, "Yeah, me too."
His face fell, as if he his phone had suddenly become somewhat less special. He looked down at it, then turned and walked away quietly, heading back down the deck. We didn't see him the rest of the day.
The Sun and Moon, on the other hand, met right where we expected them to be.
