Simple: [censored] [censored] up.
I couldn't have said it better myself.
In all actuality, the main focus of my plan is to protect my girlfriend at all costs. I'm a pretty good shot with any gun (unless it's a muzzle loader :yuck:) and I'm even better with a compound bow. Top that off with my extensive knowledge of the geography of the surrounding area and we'll be good to go.
Also, in an apocalyptic situation, be it zombies, nuclear fallout, etc., I wouldn't take crap from anybody. If someone tries to cross me, they're as good as dead.
