Its a strange one. With the amount of missing people im convinced that if someone was to look long enough that would find some clue on google maps of something.
A car in the woods or the bottom of a stream in the middle of nowhere perhaps.
Just the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown.
