No, don't go to the military base. Don't you ever read books? If you did, you would know that in the event of a civilization collapse, all military units immediately turn cannibal, demanding absolute loyalty and to prove it you have to do something weird like rape a virgin and then eat her liver, or something equally gross. Group marriages and a strict heirarchy rules, with the strongest leaders ruling with an iron fist because the only way to get "promoted" is to kill the guy above you. It all works great until some mutant virus or skin disorder takes hold and then the military unit starts rampaging around the countryside.
Every time. It happens every single time. And I almost forgot, they always lose. Even though they started out highly trained and their leaders are really smart before the disaster, and they have nearly absolute loyalty because of the previously mentioned grody membership rituals, they still lose. And they lose badly, dying horrible deaths.
Not me... I'm gonna dive into my underground bunker and wait for a couple of years. Even zombies will run out of things to eat before my well stocked secret underground lair will run out of food. The best advice is to hole up and wait it out. Let the military cannibals, do-gooder hero types, freaked out vacationing college students and their yuppie banker dads, and zombies fight it out. If the people who win aren't civilized enough to know how to grow food, they'll be dead by the time my bunker supplies are depleted.
