I'd gather as much ammo as I could and batten down the hatches. Thankfully I live in a very rural area so there are only about 500 people in my town...and I've got more ammo than that right now. Other than that, I'd raid the grocery store and steal all the canned food. There are enough cows and deer around here that I wouldn't lack any meat (thankfully I know how to butcher them LOL).
Other than that, I'm pretty anti-social so I'd be content to be by myself or with my family alone.
