Interactive Boston Marathon Map

I found this map: http://www.boston.com/sports/marathon/map_interactive/

There are tabs on the top of the map that show you miles, communities, stages, start and finish... and discribes each of them. Click on the markers on the map to read the discription, and of course you can zoom into the map to view it larger.

I think this will help me as I become more familiar with the course, and also can help spectators, like my parents who will be here watching.

I like maps, if anyone knows of any other good ones, let me know!
