I'd pack necessities in my laptop bag and backpack, staying at my dad's place (cherry farm)
I'd pick up any canned food I can, we have a dam and a water filter, it's hooked up to all of the taps, so all we'd need is a generator!
I'd use wooden spears as a main weapon, as they offer plenty of reach, can be stabbed into the heads and can be thrown.
I'd use my dad's .22 rifle as a long range and a hatchet as a close-range (if needed, ie: spear stuck)
My dad also has some nice possum traps, an air rifle, shotgun and a higher caliber rifle (not sure which)
I'd probably spend the rest of my money buying books, both for skills and some fiction for entertainment =P.
