Mama Bear Sends Tourists Running in Yellowstone

Tourists in Yellowstone National Park got a little too close to the wildlife this week, and one mother just couldn't bear it.
A watchful black bear sow sent the curious onlookers running after they crowded her three cubs in a section of the park in Montana. Wildlife and Parks Manager Bob Gibson told NBC News, "These tourists were absolutely in danger. Black bears are usually shy of people. But you put them with their cubs and they get really protective. Gibson advises visitors to Yellowstone to stay as far away from the bears as possible, especially in the spring when cubs are born and in the fall when the bears are getting ready to hibernate and are more protective of their food sources.
