I too was nine years old in 1963 and in attendance at Pasadena. The heat was brutal. Since our family was on vacation and from outside of California we took one day out of the eight to go to Disneyland. Much better use of our time. At the same time as we were in Pasadena, Billy Graham was holding a crusade across town at the Los Angeles Coliseum. We outdrew him which was proof of God's favor on us. The smog was really bad, after 8 days my lungs (unused to Los Angeles air) were hurting. I got sick one day from bad cafeteria food. Fred Franz gave what seemed like a ten hour talk one night (probably only three) on the subject Babylon the Great Has Fallen, God's Kingdom Rules. The book by the same name was released. I wonder how much if anything in that book is still taught as "truth" by Jehovahs Witnesses.
Brutal heat, rain, food poisoning, smog, unbearably long and boring talks -- what a blessing!!?? At least I got to go to Disneyland.
