The Marfa Mystery Lights. This was one of the wildest things I've ever seen. There are all sorts of theories explaining this phenomenon: scientific, metaphysic, science fiction. My favorite is that these are the ghosts of Conquistadors, still searching for gold.
As the sun set over Marfa, people gathered at the viewing sight outside of Alpine, Texas, all waiting for the arrival of the big mystery. I looked out into the horizon with the others, and heard Brenda ringing the bell from the parking lot. "What's that, a train?" a teenage guy asked his friend. "No, that's the bell lady." "Shut up," the other said. "No. Seriously. There's a lady with a bell. Go out and take a look." His friend looked at him skeptically, then took off to get a look for himself, as if the Bell Lady was as much of an extraterrestrial phenomenon as the lights.
