I am packed. (I need a medium sized suitcase. The big one is too big, the small one is too small. My stuff is in the big one and I have a feeling it's going to be one giant wrinkle when I unpack....)
Cell phone is charging.
Boarding passes are printed and stashed in my bag. 
 Reading materials have been selected: Jasper Fforde's 
Thursday Next: First Among Sequels and Patrick O'Brien's 
Post Captain (read it before, but I suspect I'll blow through the Fforde before I get where I'm going) for the outbound leg, David McCullough's 
Mornings on Horseback for the return trip.
 I hope I have time to do a museum trip into DC: the National Gallery of Art has an 
exhibition on Pompeii.I've also been informed that my nephews got a Wii for Christmas and are dying to play with me. 
And now I am going to set my alarm for 0-dark-hundred and try to get some shut-eye.
