Thing about the midwest is you can pick off the zombies from miles away. Food is easily growable, providing you put yourself in an area with moderate rainfall. As for ammo? You will run out. Build yourself a crossbow, use sticks and bones and shit(not literally:/) for ammo, then when you can, venture to civilization, find ammo, find survivors who are uninfected and go back. Make sure to take your whole party, and anything that would attract an infected so you are not overwhelmed when you return. One of my friends said he would go to a Boy Scouts camp in New Mexico, I can't quite remember what it's called, but it's supposed a huge, flat, barren, lifeless area with lots, and lots of gun, ammo, and food and water. Another good way to go, settle on the lower west coast of America(Or the lower east cost of Asia), stay a little while building up supplies, then build a ship(not a boat, a huge ship for sailing), sail it across the ocean and find yourself a nice tropical island with lots of life and no human settlement. No people, no contact, no zombies! (Unless the zombies are created using necromancy, but that's a whole different girl). Food will be plentlyful, you can get water using rainfall, in island freshwater bodies, purifying the ocean water, or a combination of the three. The food would come from the various fruit on the islands. Also, bring all kinds of seeds, and a few species of animals. Rabbits for breeding for food, dogs or company(even if you venture out in a party), tamed birds for conversation, cows for milk and meat, horses for transportation, and, other people (endless possibilities.). Make sure you bring your loved ones and friends so that being so worried doesn't make you sick. A zombie apocalypse is also a great time to express you feelings for someone if they don't already know it.
Hope this doesn't make me sound creepy, if it does, I'm sorry, but that post made you sound so sexy, OTD IMO
3 things:
1) You aren't likely to be able to captain a boat with sizable supplies alone, or with a small crew.
2) Coastal towns with ships you can pilot are likely to be resort towns that have decent populations = plenty of zombies. Mind your zpsm ratio (Zombies per square mile). You want to stay in areas with a low zpsm, so if you do encounter problems, they are likely to be limited in numbers.
3) If anything happens to the boat, then you are screwed. No ones going to come save you. Avoid putting yourself in a situation that you might not be able to fix yourself.
The plains are a good place. Find flat farmland. Have a pair of binoculars. Ensure that you have clear line of sight for 5 miles (bulldoze if necessary... CAREFULLY!). Survey the entire horizon 4 times per day.
The last time you survey the horizon should be 2 hours before sunset. If you see any zombies on the horizon. Drive out to them, and pick them off from a distance. Do not allow them close to your home.
If you killed zombies after the last survey, then survey again before retreating to your shelter for the night. If you spot zombies, you know that you will have to be extra careful in the morning.
The morning will be the most dangerous time. You will have to survey from the roof of your shelter structure before exiting out of the building. Survey the horizon, and then around the structure. Listen. Most of the world should be dead, so any unusual noise likely indicates zombies.
As for weaponry:
Learn to make a bow.
Learn to service a bow.
Learn to fletch arrows. (Never recover arrows from a dead zombie. They may not be completely dead. More than that, you will not be entirely sure how the virus is spread, so avoid any physical contact with any zombie body or goo.)
Just my thoughts.
