I was reading some online undergraduate newspaper by Penn U and came across an article about Google, and Google Earth, so I decided to investigate.  GPS systems are amazing, are they not?  Eerily stalkerish, yes, but still!  My dad was amazed and kinda took the computer away from me and announced that he was going to look for crop circles.  That didn't last long, lol.  You can even see things like swimming pools and school bus(s)es!
