Yay Gmaps Pedometer.

I'm sure there have been many versions of this for since the day google decided to make it a webservice, but I just discovered Gmap Pedometer.

It's cool! you can arbitrarily create routes on a map and save them for later. As an example here is the route we'll take to gasworks tommorrow: http://www.gmap-pedometer.com/?r=1782500

The next idea that I am sure exists is a digg-style site where people can bump up or down a user posted route. Then you can find good little routes to spend a day on. Slap on a forum, get some cred in the community and boom! You have a full fledged monetizable site. Though monetizing and cred are at odds with each other.
