I have an unloaded pistol and one backup food supply (jerky). I choose option 1.

I don't think pressing on is a good option. Old pallets mean nasty splinters and rusty nails, and I don't think I could sleep very well in a tree - I'd be too worried about falling out. So I'll try my luck in the bushes, even though I know this location is the most easily accessible to bad people/things.

Incidentally, are those who found the can of beans going to have to find a tool of some sort to open it before they can eat it? Let's see.
