When I look at the mountains here in Colorado they're so beautiful. You have potential habitat everywhere, but there aren't any bears. It's not grizzly country any more. The last grizzly in Colorado was killed by a bow-hunter in 1979.
When you're in grizzly country, you're in the wildest country we have left in North America. When there's a healthy population of bears, it's an indication that the ecosystem is healthy. That country is going to be wild. It's going to be as pristine as it can be in the modern age.
Also, students have moved away from home, where they have acquired some immunity to the bugs around them, and into accommodation shared with people from all over the country and abroad, where they will come into contact with a new pool of potential infections.
