When the idea came to me for the 72-hour shoot-in in 1973 I was pressed by the deadline for entering an international contest and thought that a shotgun approach of having 36 female models (and several male models), shooting one every two hours, could result in shot or two I could enter. The marathon was successful, though I didn't sleep a wink for the 72 hours, being super awake and alert after about 50 hours, I functioned well. Terry Oblander wrote a story, you can open it in Microsoft WORD or in WORDPAD. Have fun.
