I never heard the “n” word used daily by natives of a city until I moved to Boston while attending college. Yes, I’m from the South.
In 2001, my husband and I went to the Northeast to visit friends. We planned to visit Boston for a few days. On the plane ride up I was reading the Fromers (or Zagat) Guide to Boston, and it warned African-Americans that they should not venture into South Boston. I was shocked. No travel guides for New Orleans would ever think to mention to whites what neighborhoods they should stay away from.
