...but very effective, I am sure. If I were driving on that road, I would instantly drop my speed pretty fast!

Wonder if these sort of funny signs are by real authorities or just individual pranksters.

"Sniper" could refer to a radar or laser unit used for traffic monitoring. Or, maybe it was a particular law enforcement individual named "Bob Sniper", or a nickname for him, like "Sniper" Bob.

DISCLAIMER: The use of the common name "Bob" is purely coincidental and is in no way an inference that it is intended to apply to any person real or imagined, living or dead, named or called "Bob".
