I was just thinking about how people still go to Roswell, NM to visit the alien museum and yet those UFO sighting events took place decades ago.
Imagine if new sightings took place frequently in some town. That would probably change the local economy of the town.
I would invest after the UFOs
With enough of them, property values will go down as people move away
Once it’s identified as a hoax, the value will correct itself over time
