Google Maps has added a feature that allows you to get directions, and then by dragging and dropping points, instantly update and change the route and the information. Great for planning walking field trips at school. For example a popular trip for our teachers is to visit the Cooley Art Gallery at Reed College. Reed is less than a mile away. If you type in a request for driving directions, you get a pretty good route by car, but since we are walking, we need to adjust the map. Just click on the blue route marker and drag and the route is automatically updated. A video from Google below shows how easy this is.
