Well, here's a true, relevant, story. When I was fourteen and living in Kansas City, Missouri (my father was transferred there for four years from the Canadian Air Force), I was in the boy scouts, and every summer we used to go a big jamboree camp in the middle of Missouri. A number of the troops were from the inner city of Kansas City and were all black. We were in segregated campsites, but since they were campsites, it never occurred to me what was going on. It got very hot that summer, and there were complaints that the schedule for the swimming pool was such that we only got to go every other day. They had a meeting of the scout masters one evening, and the chief of our troop, who also happened to be a buddy of mine (a Canadian adjutant) came back to our camp at the end of the evening, and sat down beside me at the campfire completely shaken. I said, what is wrong? And he said, you won't believe this, but there is a secret rule that they can't change the schedule to have us go every day, because they have to drain the pool every day after the black scouts swim in it, and refill it for the white scouts the next day, and it would take too long to keep doing it every few hours.
