Bob Barker, who knows when the price is right, is calling for economic war against the Milwaukee County Zoo. The host of "The Price Is Right" is a strident animal rights activist and is upset that zoo officials sent a 40-year-old elephant named Lota to a facility in Illinois because she had become a discipline problem. Barker, who will be in Milwaukee Jan. 5 for a demonstration on Lota's behalf, says that returning the elephant to the zoo would lift "the black cloud that's hanging over your city." In the meantime, he's calling for a boycott of the zoo. "The one thing these people understand is money," Barker said.
