Post apocalyptic fiction

47. War Day by Whitley Strieber & James Kunetka

I read this almost 30-years ago.

From Amazon:

The unthinkable happened five years ago and now two writers have set out to find what's left of America. New York, Washington D.C., San Antonio, and parts of the Central and Western states are gone, and famine, epidemics, border wars and radiation diseases have devastated the countryside in between. It was a "limited" nuclear war, just a 36-minute exchange of missiles that abruptly ended when the superpowers' communication systems broke down. But Warday destroyed much of civilization. Whitley Strieber and James Kunetka, old friends and writers, take a dangerous odyssey across the former United States, sometimes hopeful that a new, peaceful world can be built over the old, sometimes despairing over the immense losses and embittered people they meet.
