So if you don't already know this stealth is going to be a big part of surviving so what would you do, take everything into account and use what you have around your house.
for me I'd good with a black long sleeve shirt, my dark blue fur coat, thin thermal pants with black combat pants. sure it's the winter now but if I make it to the summer everything still has a use.
I'd try and get a M9 and a 30.30 lever action rifle, both are light and the M9 can have a suppressor and ammo is easy to come by.
I'd get a nice marine issue bag because of the space. next I would try and keep the metal cans goods to a minimum when traveling. they'd make to much noise and would be heavy in numbers, so MREs would be good. I have a decent sized camel pack that I run with so that could go over the bag.
