I was at the Kansas City assembly also, camped out in the farmer's field. We rented one of those big canvas tents that were so hot. There were makeshift showers set up, women's and men's separate, with big black plastic sheets dividing it up for privacy. And riding the bus. I was 17 years old.
I remember talking to a girl about my age who was also camped out at the farmer's field and her telling me about her brother who had been disfellowshipped, had gotten into all kinds of trouble and murdered someone and went to prison. As far as the assembly itself, I do not remember what was talked about. Probably was as boring then as it is now.
