It was a VERY hot day in June in Dallas TX back in 1982. I got to the concert early and saw the nervous scads of security volunteers checking bags for booze and cameras. I cautiously looked at them and then at my 20 pound camera bag I had slung over my shoulder and thought... No way. Two Cannon F1's, motor drives, Telephotos, wide angles, 20 rolls of film... Not a chance.
