Businessweek/Bloomberg list of America's best cities: Omaha was 48th with worst air of the bunch; Lincoln was 34th with the best; no Iowa city made the cut

Hazel Abel, after whom a residence hall at the University of Nebraska, Lincoln
is named, was a construction heiress who donated a quarter-block park to
the city after personally rounding up a fountain, gazebo, wrought-iron fence,
lamps and other accoutrements which she had disassembled, shipped from
France, and reassembled at 18th & E Streets. Click picture to enlarge,
or see an interactive panorama of the park.

Left: Hazel Abel Park, Lincoln, Nebraska.
     They only looked at the 100 largest cities, so the net wasn't cast as wide as you might think.
      Not a single city in Iowa was named.
     Nebraska placed twice; Omaha just made the cut, but its air quality was foulest on the list, worse than New York, L.A., Chicago, Philly or Atlanta.
     Lincoln tied Tampa at 34, with the best air quality of the 50, ahead of runner-up Honolulu.
     Interestingly, San Antonio beat Dallas because of both a better economy and lower crime.
     Unsurprisingly, Madison, WI, one of the most attractive cities AKSARBENT has ever seen (even in Winter) placed high on the list at 17th.
