Rural mountain communities would be perfectly fine provided they don't get radioactive acid rain or huge dustbowls from urban centers. Having a month's supply of water and enough food for 2-3 months with a CBRN filter and gas mask would be enough to get you through the worst of it.
The hard part is getting consistent food and properly filtering water afterwards.
