Having to been to all five cities numerous times, I would say the readers got it right, although I would switch Charleston to #1 and SF to #2.
Besides many Europeans and East coast folks, my neighborhood here in San Diego is loaded with San Francisco
transplants.
Retired people, young and middle age professionals.
A couple I was talking with today orig. from Frisco and Berkley grads. The place is an arm pit and glad to get out.
