The rest of the article (it's short) along with a picture: http://www.cnn.com/2006/TECH/science....ap/index.htmlPITTSBURGH, Pennsylvania (AP) -- Two polar bears at the Pittsburgh Zoo & PPG Aquarium should be resting easier these days.
The zoo has unveiled a $14 million exhibit for the animals that includes a waterfall, a freshwater stream and a 150,000-gallon pool chilled to between 50 and 55 degrees Fahrenheit. It also features a yard where they can play or nap.
