As an older fart, who remembers those 3-line tiny classified ads in the back of Guns Magazine, I find it poingnant, almost sad, as the confluence of a Depression-era 6th grade education runaway to the Army at age 16 Cav. farrier mechanical genious, his old shop, and his grandsons still carrying on the trade, simply is not happening anymore. It simply can't.

And now, aging people, aging equipment. Am so glad that documentary was shot to preserve the history in more than stills and written pages.
