Never before have I been to Michigan. I left VA this morning at 6 AM, on a flight with about fifteen passengers of a possible 80? or so. It makes me wonder why short, domestic airfares continue to be $300 roundtrip when the airlines have so much trouble selling seats. Or for that matter why I’ve been having so much trouble finding tickets. Further, I set off the automatic lights on my way to the end of the main concourse in Dulles at about 4:30. Apparently most sane people do not go to hang out in the airport at such a time.

Detroit was just a one-hour, fifteen-minute flight away. I guess it’s one of those uni-airline airports, because I have not seen any airlines but Northwest and affiliated friends.

In the underground walkway between Concourses A and B&C, the kind with the people-movers, the walls are coloured and flash corresponding to the music playing. When I first entered the lights twinkled and shifted merrily like an aurora; as I left the music became more dynamic and the lights changed to fit the tone of the piece, the left wall an angry, pulsing red with the low register and the right wall a softer aqua when the higher instruments answered.

I feel I must be spending too much time in airports when I start to sing along with the muzak.

When traveling I spend a lot of time thinking about inertial and non-inertial reference frames.
