A friend sent me a link to a website dedicated to identifying abandoned and little known airport sites around the U.S. The old airports are identified by State, then by region, then locale and name. The info include Lat/Lon, old photos, old aviation charts and local maps depicting the airport, some history of the site and other pertinent info.

I did a BCP search and did not find any reference to this site, but I apologize if it has been mentioned previously.
