Drove more or less straight through, occasionally cat-napping at rest stops. Added four new states to the geocaching list: Tennessee, Virginia, West Virginia, and Maryland. The most frustrating part of the trip was a side jaunt into southeast West Virginia (for no other reason than to geocache) where both phone services (T-Mobile on the phone, AT&T on the iPad) went dark in the mountains and that meant no phone, no maps, and no geocaching services: five hours in W-VA and only one geocache found, and that was at the welcome center at the border. But the mountains on Saturday morning were just beautiful.
Got to Fort Meade at eleven Sunday morning with almost exactly 1500 miles on the trip odometer, arranged for a room on base, and found that check-in wasn't until six. But Teen Daughter the Elder was delighted to see her father (or perhaps it was the car) and we ran around all afternoon and she didn't seem to mind that her dad smelled like an old boot.
Sunday morning we had breakfast and ran around a little more and then bid farewell at BWI where modern air transportation technology whisked Southern Man back across the country with its usual tedious efficieny and he was tucked into his very own bed by eleven that evening.
It was a great trip and a lot of fun.
