Austin. Southwest Airlines goes there, and you can check two bags at no extra cost. I'm going to refresh the thread.

I'm glad you liked hearing about our trip.

Another high point - we visited Crystal Cave, a cave which has been a family-operated attraction since 1971. We went through with a group of refreshingly innocent teenagers. It was fun seeing their reactions. I've seen more impressive caves elsewhere, but it was still worth visiting.

At one place in the cave, we could look up and trace a fault in rocks overhead. For the DH and me, both geologists, it was a moving thing to look up at an actual fault in the earth, in place, in beautiful shape, and from below. It was rather like seeing a wild animal in its habitat, rather than on TV or in the zoo.

If we think of the earth as an assembled structure, then a fault would be something like a hinge. In the cave, we had the chance to see "the hardware of the earth."
