Gotham: America's Dirtiest City

So says Travel + Leisure:

After ranking a tidier No. 5 last year, NYC has regained its No. 1 spot for grit and grime. Some have argued that littering fines here—up to 10 days in jail—should be tougher, but pollution isn’t always just what you see or smell: New York also won the survey for being the loudest and rudest city. Plenty of voters embrace that over-the-top personality, however: the city also ranked first for its theater, stylish locals, and luxury stores.

The rest of the dirty top ten, in order: New Orleans, Baltimore, Los Angeles, Atlanta, Philadelphia, Dallas/Fort Worth, Miami, Memphis, Houston.
