There’s a brand-new website from the evil geniuses who brought you the world famous Ride Lugged blog:
The Dirt Road Database is a gmaps-mashup type thing to share the locations of dirt roads that are nice to ride bicycles on.
I like the idea. I’m not thrilled about using gmaps-mashups generally, but OSM isn’t quite in a state where this would work….yet.
Anyhow, if you are looking for dirt roads in your neighborhood, or want to tell the world about your favorite dirt roads, check out the Dirt Road Database.
 Richard Fairhurst’s talk, Why Mashups Suck (and Cartogrpahy matters) is an excellent discussion about this.
