Here is a brief look at what some other countries say about American big cities in order to warn travelers:
Well, just as State warns Americans about dangerous places to travel, so too do foreign ministries in other countries — and some countries warn their citizens to avoid heading to certain cities in the U.S. France, in particular, warns travelers to be careful in a large number of specific cities…
Chicago: Stay away from the West Side and anywhere south of 59th Street…
Boston: Avoid walking at night in Dorchester, Mattapan and Roxbury, and be wary of “petty crime” in Chinatown, the North End and Fenway.
New York: Be wary in Times Square and at the Statue of Liberty, and don’t go to Harlem, the Bronx or Central Park at night.
Washington: Northeast and Southeast should be avoided, and Union Station is dangerous at night. “Le quartier Anacostia n’est pas recommandable de jour comme de nuit.” Translation: Don’t go to Anacostia, day or night.
Interesting instructions that seem to be based around avoiding poorer or higher-crime areas of big cities. Perhaps the better question is how many Americans would give the same instructions to family members or friends.
