“Garrett County is hardly colder than Detroit – hardly colder in 2002, for that matter, when I had the conversation, than it had been in 1890, when it had 185 African Americans. The fact that the very next county to the east had more than 1,000 African Americans, while Garrett County had at most one black household, is a dead giveaway. Such abrupt disparities can only result from different racial policies, not from factors such as climate.”
