"
In such isolated high country, away from
opprobrious comment and watchful eyes, I thought it would be plausible for the characters to get
into a sexual situation. That's noth
ing new or
out of the ordinary; livestock workers have a blunt and full understand
ing of the sexual behaviors of man and beast."
-- Annie Proulx, Brokeback Mountain: From Story to Screenplay, "Getting Movied"
