Google Walking Directions - Works in Chicago!

I just tried out the new Google Walking Directions. Supposedly, Chicago is a walker's paradise - pretty flat, pretty safe in the daytime in most areas, lots to see and do by foot, etc. So, I just went to Google Maps and asked for directions from Union Station to Water Tower Place (doesn't matter at this point whether you want driving or walking directions). After you verify the two end points of the directions, you get the choice for driving or walking. The end results give you the directions, a map with the path plotted for you, and an estimated time - 42 minutes for this walk. Pretty nice!
