Another substandard polar bear exhibit closed down. As with elephants it's been interesting to see which zoos shell out millions to build state-of-the-art habitats for the Arctic bears to keep up with rising standards and levels of naturalism and which ones opt for phasing out. As Cleveland,Tulsa, Reid Park, Central Park, Roger Williams Park and now Indianapolis have given up, zoos like Columbus, Saint Louis, Hogle, Kansas City, Henry Vilas, Brookfield, Louisville and Buffalo have spent the money.
