  :Well, Currently the zoos polar Bears have been relocated temperarily to make way for the new Glacier Run polar bear exhibit ( so they are doing something about the old exhibit they have had for years ) and i think this zoo is a very good zoo compared to others i have seen..   I visit this zoo on a weekly basis since living in Louisville and really don't think this zoo is as bad as your trying to say it is..  They have several new and remodeled exhibits within the past 3 years that i have lived in Louisville, so i could say that i believe it has changed in last 5 - 10 years..  The seals and sea lions have also been relocated as their new home will also be within the new Glacier Run exhibit..  a link with information about the new Glacier Run Exhibit is located here. http://www.louisvillezoo.org/glacierrun/  And they rely on donations to be able to improve those animal exhibits...
