The little restaurant at the museum had nifty under-lit tables. Very futuristic. Mediocre food, though. :-)
After lunch, we headed back to the hotel, where we waited in the lobby for Patrick to arrive to give us a lift to Cambridge.
I was a little worried when he showed up, because his midsize-sedan car was already packed to the gills with his stuff, and for a while I was worried our suitcases wouldn't fit. We'd deliberately traveled light; each of us had only one small suitcase (small enough to count as a carry-on for the airlines) and a handbag-sized case for odds and ends. But there's only so much you can do with the limited space in a car...
But we triumphed over the limitations of physics and the space-time continuum, and managed to cram the four of us and all the gear in there. I rode the entire way to Cambridge with a large 4WD electric RC truck on my lap. More on the truck later...
