One thing about staying in town, is any lights, cooking etc will be a swift target.
People will have quick access to the source with little effort. If staying and wow if its winter this will be a whole big issue
how do you stay warm with no fire, no wood , and without being spotted ?
Stay below a couple thousand feet.
We spent 2 weeks in a snow cave.
It can be unpleasant if you dont prepare.
Get rid of everything not synthetic.
Learn ! prepare, practice. Real life is far from talk and thought. Learn your foods... ...... make a broth from some plants, you wont wake up again ! Nearly all insects and larve are edible, but some also bite back. There is one huge salad in the PNW.
Keep lots of salt and vinegar. for Disinfectant and also food cure. Stay clear of all still water unless you can filter it. There are things there that will eat you from the inside out. Boil or filter all open water. This list could be a hundred pages long, so educate yourself.
