Indeed! A HELLUVA lot of work, but I believe he's worked on it over at least several years.
I sent the link to one of my oldest & dearest friends today, on whose ranch I lived in an outbuilding for several years, who has learned one of our local Native American languages and is the local "white man" expert so that he can provide that information and history for the site owner to include. I am very much looking forward to seeing our local information reflected.
I'm really into this sort of thing, and I love our local history with the native cultures. It fascinates me.
