Doug Moe: Harry Crews was a writer's writer. (Wisconsin State Journal, 4/23/2012)

This was not a recipe for successful personal relationships, and Crews’ life away from the typewriter — and, notably, the classroom, where he was a revered writing teacher at the University of Florida — was chaotic.

Blood and Grits contains the essay, "Going Down in Valdeez", first published in the February 1975 issue of Playboy. It was Doug Moe's introduction to the writing of Harry Crews. (See! Some people do read Playboy for the articles.)
