A WWII vet once told me that after a battle, you could have walked from one end of the field to the other without touching the ground, walking on bodies.
After Mount St. Helens blew I walked from one mountain to another without touching the ground, walking on downed trees.
An old-timer told me that that you used to be able to cross the Carpinteria Valley without touching the ground, the coast live oaks were so numerous.
And you can cross Beijing and never lose sight of a KFC. Which is why, I suppose, all those soldiers had to die.
