Lake Superior Zoo reopening

It's been more than three weeks now since Feisty the seal and Berlin the polar bear rode the floodwaters out of their zoo enclosure and into a media spotlight. Their Polar Shores exhibit remains empty while officials at the Duluth zoo decide whether to revive it. But the rest of the Lake Superior Zoo reopens to visitors Friday for the first time since the flood. One official calls it a step toward a return to normalcy.
