I suppose it's difficult to anticipate such things as earthquakes and nuclear war but in our case we had warning in the form of weather forcasts. Having Empty containers we would have been able to fill on the spur of the moment, water, gasoline, food, etc. Next time I will take these forcasts a little more seriously. Live and, hopefully, learn.
even apartment dwellers have a tub that can be filled on the spur of the moment.
