We gave up listing books when a nearby thunderstorm started booming around 3:30 PM. We jumped in the car and drove to the Post Office instead. We unplugged the computer to keep it from getting fried, but the storm sort of edged around us, dampening the ground slightly, but not really doing anything besides dropping the temperature. We are debating about working late tonight, since we found some more books while moving around some older boxes in inventory.
