Schuyler's question is interesting, however, he misuses the concept of
"folk," putting it on a par with non-cultural phenomena at the opposite end
of a spectrum from what he described as "cultural-social."

He is correct in dubbing some of the "attractions" in his notes
"idiosyncratic," however that very term implies that the object/site is not
folk (or vernacular). In the world of professional folklore, folks studying
material culture often struggle with popular misconceptions that outsider
art or self-taught art is folk art. It is not; it is idiosyncratic. The
stone castles or pleasure gardens, including such places as artist Howard
Finster's "Paradise Garden" <http://www.finster.com/paradise%20gardens.htm>,
carry a folk label but are actually not tied to any community or cultural
tradition that the word folk implies.
