If an invasion occured , I'd take my dad's E-150 truck and fill it with any weapons I might consider effective (hatchets, axes, shovels, sledgehammer), food with a long shelf life, tools to upgrade my vehicle and/or a building later on (gotta get outta there fast), and extra fuel. Then I'd go in my house and grab my camping stuff (firestarter, rope, etc.), my 9" survival knife, staff, two bayonets, and possibly bow(s) and arrows. Then I'd drive around and look for friends that I know wouldn't betray me, arm them with more bows, then get out of my hometown. I'd then drive away from there so I wouldn't have to kill my zombified friends, and therfore deal with grief. Beyond that, I'd spelunk stores for rifles, arrows, food, clothing, etc. until I get to a refugee camp or get someplace where the infection couldn't thrive but still know what's going on around in the world.
