lets be honest. will smith did a good job in the movie, but his character lacked common sense. hopefully, this instructable should help you if you ever find yourself in his position.
Step 1: Materials
military vehicles: there should be plenty of humvees and tanks left in the city from the
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.
Step 2: Food
for food, dont just go around to random houses and take their food. even if they are ether dead or infected, it is still stealing. also, you dont know how long that food has been there. for all you know, it could be years past its expiration date. usually, tanks carry excessive MREs for the crews, so of course, with the former massive military presence, there should be plenty of extra food.
Step 3: Keeping Yourself Sane
if you are going to try to keep yourself saner in this post apocalyptic world, dont surround yourself with dressing store mannequins. it will just add to the image of insanity.
Step 4: DONT TRUST FRED!!!!!!!!!!!!!!
if you feel the absolute need to have mannequin companionship, dont trust fred when he moves across the city. he is definitely working with the infected to kill you. look how well it worked for will smith.
Step 5: Home Defense:
this is one of the few points in the movie he did somewhat well on. rigging the cars outside to blow was a good idea. to better protect yourself, though, i would also have a very high electric fence. the infected are still alive, no matter how much they seem like dawn of the dead zombies, so a good sized electric fence should keep them out. or a high voltage electtric moat.
Step 6: Dont Steal the Alpha Males Mate.
will smith did this to find a new test subject. long story short, the alpha male got ticked when he realized he lost his woman, and neville ended up getting blown up for it.
Step 7: Read the Book.
if you are in this kind of situation, it might be a good idea to read Richard Matheson's book. it is basically an instruction manual on what not to do. it might also give you some helpful ideas.
Step 8: Go to Vermont.
follow the idea to go to vermont much earlier. it is nice up there, and full f people who are not half braindead zombie-like creatures. (no offense to the half braindead zombie-like crteatures who are sitting behind their computers all day. get out of your room and do something.)
Step 9: More to Come Soon.
this is only the beginning of the instructable. there will be more as soon as i think of more ways to keep yourself alive for more than 3 years after the collapse of humanity.
