People of northwestern Montana have been advised to be on the lookout for drunken bears. Black bears and grizzlies have been congregating along the tracks of the Burlington Northern railroad tracks, where a train carrying hundreds of tons of corn derailed some time ago. The corn has fermented, and the aroma is attracting the bears. "The bears are actually intoxicated up there," said wildlife biologist Loren Hicks. And a grizzly with a hangover can be cross as a bear.
