I discovered the Maysles brothers' 1975 documentary Grey Gardens in my first semester of busines school. My marketing professor showed us Salesman, and it floored me, leaving me to track down the rest of the Maysles' work.
So I can't believe that it's taken me this long to finally read Gail Sheehy's 1972 New York article on Grey Gardens and the Edie Beales. I wish I'd found it when I was living in East Hampton; would've made those winter nights that much crazier.
