The City of Portland, Oregon has a web site that will display a map of the area, much like Google. However, they have a dozen different layers of information you can overlay so you can see their impact on your area of interest. Very cool. They do want a location before they will show you anything, but they give you a sample one, and it works to get you downtown. From there, you are free to explore.
Came across this while looking for information on car break-ins. One of my wife's co-workers had a window smashed in her car and her bag of stuff stolen while she was at an early morning exercise class in downtown Portland. Apparently teachers are not the only ones who get up early.
