Leave the coast with a plan
Fruit trees and a well beat a gunfight on the pier. Inland towns have clothes that actually keep you warm. Keep additional game information nearby when a new official map still confuses spawn lines.
Food, rain, and a quiet stash
Cook meat. Dry clothes. A cold rain with no hat is a slow death. A buried stash beats a backpack you will drop in a firefight. See related resources for extra notes on sickness and charcoal.
