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.
