After more than a decade kayaking flat water, Daniel Hartung wanted to try some rapids. His opportunity came during a bluegrass and whitewater festival in Hope, Alaska.

He drifted until his foot was snagged in an underwater branch. Then things got worse.We also talk to an Alaskan travel expert about how to safely experience the ruggedness of the Far North.
