TSA == Transport Security Administration.
You remember last night I confessed I'd bought a cask of wine to bring with me to Dallas? Well when I opened my suitcase tonight I found the standard TSA 'we opened your luggage for a security check' disclaimer. Fine. I've seen that more than once before. But they were very thorough this time. They'd opened the wine cask, taken the plastic wine container out, presumably felt if it contained solids (and undoubtedly laughed). Then they put it back in the cardboard box and taped it back together!
I don't have a problem with this though; it proves they're doing their job!
