http://www.jaunted.com/story/2011/6...isure'+Delves+Into+America's+Filthiest+Cities One of the biggest travel turn-offs is a filthy city. Having to walk through stanky, trash-strewn streets really puts a damper on the whole sightseeing experience. Travel + Leisure compiled a list of America's dirtiest cities, and a number of popular party places topped the charts, with New Orleans grabbing the No. 1 award for grossness. It's not a big surprise that the Big Easy is a Big Hot Mess; tourists flood places like Bourbon Street for Mardi Gras and leave loads of garbage, beads, alcohol and other undesirable leftovers all over the place. The mag put Philly in the No. 2 sloppy slot, and apparently it narrowly missed winning the dirty champion title. It's not a shocker that Los Angeles clinched No. 3, it's second consecutive year in that spot. The city's thick smog continues to do it in. Party city Memphis took fourth place. New York City, last year's dirtiest city winner, dropped to No. 5 this go-around. If you're wondering who filled out the rest of the top 10, sixth place belonged to Baltimore, which was deemed dirty and got low marks for its public parks; seventh went to Las Vegas, which we thought would score higher but actually bettered its standing by two since last year; eighth place was claimed by Miami, whose bumping bar scene may be a contributing factor to its lack of cleanliness; and rounding out the top 10 were Atlanta in ninth and Houston in last place.
