Unusual multicolored displays of aerial luminosity repotedly often seen
near the town of Marfa, Texas. They may have a mundane explanation (car
headlights, for instance) or, possibly, be examples of so-called earthlights.
They are seen on such a frequent basis that the residents of Marfa hold
an annual jamboree called the "Festival of Lights" to celebrate the phenomenon.
As, in the case of the Roswell Incident,
the number of visitors attracted by the purported phenomenon is certainly
good for local business, whatever the ultimate explanation.
