There are several good web sites that show maps. They can give you directions from one place to another. They can let you zoom in to see a satellite photo of the streets and surrounding buildings. And the really cool ones do a free street view that show what the front of the building looks like from the perspective of a car driving by on the street.
I’ve tried them all and I’ve tried all the GPS devices, too. My favorite out of all of them is the Bing.com maps. Try it – you will see what I mean.
