Sydney, December 1973. We drove over from Adelaide, a trip which took a couple of days.
Before the convention there were rumours going around in the local congregations that Armageddon could start during the convention. The 1975 hype was still going strong and the thought was that the "end" would come by October 1975 at the latest, so this seemed a likely time. When the bomb scare happened, there was a lot of expectation in the air.
