Google Maps is a great tool and it keeps getting better. Their public transit and walking directions are nice new feature. The walking directions are really cool because Google Maps will gladly generate walking directions for any route, no matter how ridiculous it might be. Here's a nice leisurely stroll you might want to take the next time you need to go from LA to New York but aren't in a big hurry. Google estimates that it would take you 38 days to make the 2800 mile trek (assuming you don't stop anywhere along the way).
Michelle discovered an interesting routing for her trip to Falmouth. The walking directions have you hiking all the way up to Boston, hopping on a ferry to Provincetown, and then walking all the way around Cape Cod. When we first looked at it, we thought that Google was suggesting that you walk on water from Boston to Provincetown. While it may sound like Google is copping out by including a ferry ride in the walking directions, I doubt that pedestrian traffic is allowed on the bridges that span the Cape Cod Canal, so there technically is no way to walk to Falmouth. Perhaps the next release of Google Maps will include a swimming option.
