I don't want to spoil the surprise, but the Google treasure hunt available on Google Maps sounds like an elaborate April Fool's joke. I guess we won't know for sure until later today.
The map is a digitalized version of Captain Kidd's 315-year-old treasure map, which was found last year. With the help from online users on the map, Google hopes to locate the treasure.
Personally I think this sounds too badass to be a real life expedition; a Google treasure hunt that has everyday people deciphering an ancient treasure map? I'm not saying that you shouldn't participate and be part of the magic -- I'm just saying you should be as suspicious as you would over a pirate's validity if he didn't have an eye patch and wooden leg.
