I have to thank my sister in law for this tip.  It turns out smartphones embed gps data into every picture they take.  Once you post this online that information is easily accessible and points to the EXACT location of where that picture was taken.  The site icanstalkyou.com gives information on how to disable geotagging of pictures.  Andriod phones are the easiest to kill only camera geotagging whle iphone/ipods are the most difficult.

On my Driod based phone store location was already off..:)
