Who here on this forum is actually prepping for a nuclear event? I think there are more every day and less mundane events to prep for.
I am, and yes I agree that that there are other and more likely events to prepare for, BUT most preps would also be useful for other disasters.
About the only nuclear specific preps in my case are Geiger counters, most other items are of more general use.
Food, water, clothing footwear, blankets, tools, fuel, batteries, flashlights, lanterns, camping stoves, defensive equipment and the like are of general use in an uncertain future.
In places liable to hurricanes or tornadoes a shelter is prudent against such events, by spending a little more a storm shelter could also serve as a fallout shelter.
In places liable to earthquakes or wild fires, precautions against such events are sensible, your earthquake resistant or fire resistant storage facility could also serve as a fallout shelter.
