That was a pretty cool video, thanks for sharing. I like all the household items he made from scratch....fly swatter, coat hanger, dustpan, etc. And his simple but effective system for collecting water. The winter must have been a bit harsh. At least for me it would have been, being that I've lived in warm California climate my whole life so I'm not as cold-weather hardened as some of you guys.
Oh, and the one thing I'd definitely bring is my book, the SAS Survival Handbook by John Lofty Wiseman!
