Their Home page says they are "A collaborative effort of cemetery preservation advocates working to increase public awareness and activism in preserving, protecting and restoring endangered and forgotten cemeteries worldwide."
It has a recomendation from the History Channel.
Don't know any more about them except that they included this quote (which I have not verified) - "Show me your cemeteries, and I will tell you what kind of people you have." Benjamin Franklin (1706 - 1790)
One of the programs is "Endangered Colorado Cemeteries - Submit a Endangered Cemetery Report" . Old Louisville / Superior is not listed. (?!?)
