It doesn't seem like it's been nearly four days already. Friday at 2:45 am, we watched him and his friends blearily board a bus. They'd been jumping around and talking for the previous half hour and the lateness and last minute thrashing seemed to finally wear them out. I'm betting the bus ride to Jacksonville was very quiet after they settled in.
After driving a while, they stopped for lunch, looking amazingly chipper. Then it was back on the bus and driving until nearly 9pm. That's a LONG day on a bus.
The next morning though, they were up and going. Over the next few days, they would visit a lot of museums and DC landmarks.
