Hi All-
All right, I am coming in here late, but here is my take on it-
Disclaimer: I hated this movie and am not condemning nor condoning Chris or what this kid did.
First, what everyone here seems to forget is that he did not die because he chose to stay or because he couldn't read a map, or failed to bring enough gun. He died because he mistook a poisonous plant for an edible plant. From what I read (luckily not experienced) the plant that he ate causes intestinal cramps and fatigue so bad that one cannot physically move, never mind hike in Alaskan wilderness.
As far a weapons, I would not be caught dead (or alive for that matter) in Alaska with just a 22, but, remember, he lived off of small game; squirrels, small birds, etc. Try shooting a squirrel with an '06 or a 44 an see how much edible meat is left. The moose thing was probably a lack of knowledge, but then again, one person would have a heck of a time dressing out and preserving a moose with the proper equipment. Alone in the Alaskan Bush with minimal tools, I dont think that most of us would fair any better. I think that for "survival" purposes, a 10/22 would be your best bet for gathering food. That said, I would still want a 44 mag or a very stout loaded 45 Colt on my hip.
Also, this kid was an experienced outdoorsman, I just think that he seriously underestimated Alaska.
I am not defending him, just stating what I have read.
