cool tool

So djw sent me this very cool tool that integrates with Google Maps to determine the distance of a run / walk / bike ride / swim / boat trip / hover craft ride, etc. It gives you the bird's eye view and let's you measure distances even when there may not be roads listed on the map.

Have you ever run to your office and not known the mileage?

Or been on vacation, ridden sans bike computer and wondered how far you went?

I think it is super cool, but maybe just because i always manage to break cyclocomputers.
