It's after 1 AM when we arrive at the airport and there are not too many people working in the customs or baggage area. We head for the car at around 2AM. It's about an hours ride home. There is road work and we're unable to get off on the Washington beltway - so we continue into unknown territory thinking there will be a sign to get us back from the detour. There is not - and I have left my GPS in the trunk. We find a safe place, get it out, and find our way home. It's well after 3AM. It was a great trip - I'll unpack another day.
