I am a good shot. I don't hunt.
I know where water is, and you have to ride or walk to get to it. I'd ride.
I am very familiar w the desert and how to survive in it, a place most people will not run to.
Really, the largest threats to anyone that has a modicum of survival skills, in this hypothetical dooms day scenario, is other people and fear. So, for the fear I am sunk, I can't drink or take most kinds of medication.
And, I have some stored "supplies" on my bum...so bring it on.
Seriously, I often would tell DD, "if this, then remember this" survival tips. I always thought she just pretended to listen and was actually internally rolling her eyes. But, after few recent events I found out she heard what I said after all! Someone actually took the time to come over and congratulated her on having the "sense" in one instance. People do "store" survival info, probably more than they know.
