A more serious idea than my temptation to hide a boxed ocarina in the park for unwitting musicians:

Antiquities collector Forrest Fenn says he hid the bronze chest more than a decade ago, creating a treasure hunt for people to find it.

Thousands of people searched for it, many quitting their jobs and using up their savings. Four people died.

I read this just after waking up and thought I remembered reading "hundreds of thousands," but even "thousands" seems hard to believe. And the treasure was actual treasure: valuable ancient coins, jewels and artifacts.

From what I can tell, this whole story is supplied by the architect of this hunt but sat alongside front page stories of the Coronavirus pandemic and worldwide protest marches. Is this real? What is going on?
