That was also a docudrama on Nat Geo channel awhile back, with 3 different stories of survival or not. I know that crawling in snow with a broken leg could be difficult, a lot depends on the actual terrain and conditions. Considering the time he survived, Doug really did well with what he had available. This to me really stresses the importance of carrying some emergency gear. I was on a hike Saturday with a large group and equipment carried by most looked pretty limited. Some would have had difficulty surviving this simple hike if there had been a turn in weather or an injury. I can't imagine why people venture into the wilderness with such limited preparation. Lunch, camera and a water bottle is about all the majority of the folks carried. We were as much as 5 miles from the cars and a 3 hour drive to civilization from there. These types of hiker seem to be candidates for future articles!
