Here's a question I just asked myself.

A wildfire is QUICKLY approaching you home and you have 30 minutes to evacuate. You have "grab and go" boxes containing insurance, family pictures, and other important papers; you can easily grab your laptop and the backup drives; your toiletries and medicines are simple to grab -- but you have room and weight for no more than six books.

What six books would you take? The rest of what you own will be ashes very quickly and you gotta load and scoot!
