Far South of I-10

I'm traveling from europe back to the western hemisphere and my laptop's battery died. There are power plugs in one of the houston terminal b corridors of despair, but non are near a chair so I must sit indian style on the ground, looking like an unjolly budda. I did miss a flight yesterday and get stuck in Rome. The other option was waiting six hours then flying standby to spend the night in Newark. I skipped the standby and stayed in Rome. I did a nice hike from the Vatican to the Pantheon, then through all the fori and all the way south to somebody's bath (caracella? pretty impressive ruins of a giant bathhouse)
