Dr. Dave returning soon?

The original agreement called for us guest bloggers to try to look busy until the 20th, and in exchange we'd get some not-quite-stale Hostess pastries. Well, today's the 20th, and Dr. Dave hasn't broken radio silence for a couple days. I'm not sure what to make of that. Is he getting back tonight? Tomorrow? Is he in a FEMA camp scrawling his escape plans in the dirt with a sharp stick? Will he be all rested and relaxed when he gets back, leading to lots of posts about kittens and rainbows? Or has this car trip left him all frazzled and snarling and ready to break things?

Answers, people! I need answers!
