The search for Sasquatch isn't all that much different from the search for the Ivory-Billed Woodpecker, except that in the case of the woodpecker it was at least known that it did exist some time ago, but was declared extinct quite a while back.

When a fellow came out of the swamp claiming to have seen one, there were lots of disbelievers, and hundreds(?) of people invaded the marsh forests looking for one.

The search went on ...

The frustration in not being able to find one is aptly illustrated by the expression on the face of This Guy who can't find one no matter how hard he looks.
