If you don't know of a site called “Geoguessr” then you may want to check it out. The site uses Google maps to place you anywhere in the world and then asks you “Where are you.” It then gives you points on how close your guess is to the drop point.

I was going to link my last score but I forgot to bookmark it so I guess it's lost. Either way I found guessing where I am and getting fairly close quite fun.
