If the scenario is exactly as listed above this is how I would do things. If it were say a zombie Apocalypse the order of my list of priorities would change drastically as well as additional things being added in.
Priorities
1. Find food and water source.
-Can be achieved by relocating to a safe location near a large clean river in the Northern US. Fish and animals that come to drink from river will be a renewable source of meat. Water will be available from the river as well. Trash can be bundled and sent down stream to avoid polluting the area immediately around location.
2. Find and preserve different forms of energy.
-The river can also be used with a generator to run electricity in the fortress that I will construct. Gasoline and Natural Gas will also be brought to a safe location, close to the base. A wind turbine will also be constructed for additional energy.
3. Construction of a Safe House/Fortress.
-Think giant forerunner structure haha. All construction materials at your disposal, and top of the line security equipment and appliances. Ok, most likely will find an existing structure in a desirable location as described above and simply fortify it.
4. Weapons and vehicles
-Protection and Hunting (anyone see Will Smith hunting in I am Legend?)
-Vehicles needed: Fast car of some kind with good safety rating and fuel efficient (don't waste your resources needlessly.) Motorcycle for quick light travel. Large Truck/SUV with off road capability as well as towing and hauling found supplies. Semi truck or similar that can transport construction equipment also a trailer that will be turned into portable home for extended trips. Fishing boat for river and barge for transporting goods and equipment across the river. As roads deteriorate over time the SUV will most likely become the main transportation vehicle.
5. Broadcast and Search
-Set up a broadcast tower to broadcast information to survivors.
*Key- broadcast a remote meeting location that you have under surveillance via video cameras and wire taping. This place will have lights and power and have a bright light beacon to draw people to it. Once survivors arrive you can determine if their mental state (no crazies allowed at my place) and if they are just out for your resources.
6. Entertainment and learning
-Anything your heart desires. Lots of gaming, watching movies, golf (will require mowing.) Teach yourself how to fly a plane or helicopter. Good for transportation. Can't land? Skydive. Seriously who cares where the plane crashes. Find another plane and skydive somewhere close to home.
7. Maintain Sanity.
-Keep pets and farm animals for companionship as well as food purposes (milk, cheese, eggs). Find and watch old broadcasts of the news to feel as though you are having some human interaction. Read a lot of books. Everyone is a little different so different people will try different things.
