What was also interesting about that was the background that was given during the inevitable pledge breaks. Apparently he did the longest continuous natural study of wolves ever undertaken. He also filmed all that with a Kodak movie camera with a clockwork mechanism fixed on a tripod.
He injured himself at one point and was out of the cabin for a few days, I forget how, sprained ankle I think, and he had to drag himself back to the cabin.
Really remarkable and not something that just anyone could attempt, but inspiring nevertheless.
