Sweetwater, Texas, 6/15/79. It was 107 degrees in Sweetwater -- hotter still by 10 to 20 degrees inside the aging gypsum plant built half a century earlier. Jimmy Lopez had been at work since 7 a.m., lifting hundred-pound bags of gypsum plaster off packing machines and onto a hand truck. During the portrait session, Dick said very little, simply a word or two to encourage Lopez. It wasn’t until after the end of the session, after Dick had thanked him, that he admitted almost fainting from the glare, the hot wind, and the strangeness of the situation.
