For most people, hanging off of a cliff in a tent might indicate that somewhere on a camping expedition, they had taken a wrong turn. But for a daredevil couple, scaling cliffs and pitching tents on the side of a 3,000ft cliff in the face of freezing temperatures and falling rocks is the perfect day at the office. Professional free climbers Tommy Caldwell, 35, and wife Becca, 27, of Estes Park Colorado, U.S. take on cliff faces on a daily basis, relying only on their hands, feet, and equipment to get them up the mountain.
