That's very nice, but I was thinking of more like this one.

It's hosted by Chainreaction bike store and they have quite a good cllection of the local favorite bike rides, so it's only limted to San Francisco area. It would be nice if every members of the bikeforum post photos and maps of their favorite rides all over the US and beyond, and other members can search where they want to go state by state or city by city.
