Where do you even start to clean that up?!

-Blast
Heaven only knows.
I guess I would start by removing the wrecked cars that were deposited on the top of three-storey buildings. That's so surreal that it's demoralizing. Makes you feel small, insignificant, powerless.
Beyond that, you put one foot in front of the other, then repeat. One bite at a time, and keep chewing. What else can you do?
I've read stories of searchers going through this rubble. They hope for signs of life, of course; but they know what they are going to find. Realistically, they are in the recovery business. I can hardly imagine the psychological toll.
