Step 1: Materials
former military presence. don't take the Robert Neville approach, and
take a crappy station wagon.
sports cars: leave the ford mustang. its not worth the repairs you will need to make,
especially when it breaks down miles from the shop. take a ferrari
guns: a sniper rifle does have its advanteges, but a rocket launcher works much better
for large groups. also, dont only take one grenade.
food: forget the food in stores, it will probably go bad in a couple of months. there are
probably plenty of military foods with a shelf life of about 30 years.
computer: dont use a macintosh.
