I am currently in love with this site. For example, here is an aerial view of Bridgeport, Nebraska, my husband's hometown. Care to know what the average commute time is in Bridgeport? The census information link can give that to you easily.
This is my parent's house in Lincoln. And this is a topographical map of my neighborhood in Austin.
As you can see, this site is basically awesome. Now I'm off to look up other familiar neighborhoods.
