Mountain climber and arctic explorer Lonnie Dupre has a new book out called "Life on Ice," which chronicles 25 years of Dupre's polar exploration. Fellow Minnesotan and polar explorer Ann Bancroft is getting ready for another expedition in November 2012.

We thought it would be fun to have both of them in the studio to discuss pushing the limits of polar exploration.

TOM'S TAKEAWAY

They really do think of their expedition dogs as companions, not just tools for the trip.
