preflight jitters

It's 9ish in the morning of my first full day of Freedom from School, and I'm skittering around the house gathering up items from the piles I've been making all this past week. My luggage is only at 33 lbs. What am I forgetting? The big decision right now is about books: serious work to help me understand the culture I'll soon be immersed in? novels I'll have to teach in September? or books about the evils of junk food and environmental horror stories to get me fired up on the flight to China?
