The GPS turned out to be hanging on the doorknob in its carrying case. Very little charge left, so I plugged it into the car charger on the way over to the airport.
This is the first time the little food stand inside the airport gate area has been open when I've been here. Juice, yogurt, coffee, bagels, pastry, and what turn out to be passable breakfast sandwiches. A little dry, but better start than the handful of Cheerios I had an hour ago.
