If you haven't seen google maps street view, check it out. You can "walk" down streets of major cities, turn your head right or left to look at the buildings and take a virtual walking tour of major landmarks.
I first caught wind of it when privacy concerns arose by the people caught in the street view cameras coming out of strip clubs or falling off their bikes. Soon google will be blurring faces in street view.
Below I took a stroll down Yawkey Way to the entrance to Fenway Park!
