Any frenemy cities?

I have some observations on Conde Nast Traveler's list of 2014's "friendliest" and "unfriendliest" cities in America.

On a personal note, I have been to one on each list, Telluride, Colorado and Detroit, Michigan. Drawing from my humble, first-hand experience of both cities (I lived very close to Detroit) I'd have to say this: Telluride, Colorado is bound to be "friendly" because it's not a typical city with a standard urban density of population. Telluride is a ski resort with astounding natural beauty; where nature is the dominant resident, friendliness is bound to emanate.

Detroit: How on earth can a city that has suffered multiple economic and other damages in the last decade or so be "friendly"? Consider somebody you know; a person that has been victimized by financial losses, betrayals of various kinds and harsh race politics. Would you expect that person to be a Ms. congeniality contestant? As it is that Detroit has negative media image; by labeling it as America's 5th most unfriendliest city is exacerbating the wound.

I was surprised with the omission from the list of the megapolises like NYC, San Francisco and Chicago. Perhaps they are frenemy cities?

Interestingly, Connecticut has 2 ill-tempered cities--Hartford and New Haven; some say the whole of Connecticut is cold to all those who don't belong to the 1% league.
