Atomic Chains: NaPOWRIMO 14

O, I ate a Pig's Eyeball?!

A San San to My dream Last Night:

Snow accumulated along the tracks
life after chaos echoed
Nuclear winter buses.
Snow relocations of our packs,
life after chaos bellowed.
We huddled at our leisure's 
Nuclear winter musses,
we huddled to escape zephyrs.
