Had an interesting experience 2 yrs ago. Stayed at a motel on I65 near Montgomery, Alabama on my way to Florida.
Calypso Louie was giving a speech nearby and a the motel was basically full of NoI people coming to see him.
These folks were dressed like the 1950s Sunday crowd and their kids were perfectly behaved.
The Nation of Islam people are a serious group of separatists. They are very conservative.
