It sounds odd, but in a doomsday scenario I would eat people before I died.
I was a boy scout, and raised camping and spending a LOT of time in the wilderness, I would most likely head into the forrest where it would be less dangerous. I have some camping gear, mini me and I would be safe, or at least safer.
My truck (bronco) has a big fuel cell and a huge grill guard thats bolted to the frame,
I could push things out of my way and get somewhere safe.
