But many of the people who listed a gun put it top. They are saying they'd rather have the gun than everything else; it's the last thing they'd jettison. So they'd have the gun when they didn't have any other kit to lose - no water, shelter, fire or whatever. To me this seems strange, but I suppose it depends on where you live. If I were to include a gun, it would be about halfway down.
