A Minnesota audience will be transported to the Alaskan wilds tomorrow night to experience the landscape and creatures of the Arctic National Wildlife Refuge. A traveling show of music and photography called "Caribou Commons" is stopping in St. Paul to raise support for protecting the habitat of the porcupine caribou herd. Each year some 150-thousand Caribou migrate hundreds of miles from their wintering grounds in Canada to the Alaskan coastal plain. Environmentalists are fighting to protect the herd's calving ground from oil development. Yukon writer and photographer Ken Madsen created the Caribou Commons project.
