I got hit with one of these on Friday IAH-AUS, then about a month and a half ago IAH-CLE. The guy on Friday tried to throw me for a loop, though. He asked for my ID and asked if I grew up in Houston. I grew up about 60 miles south of Houston, but most people don't know of the town, so I said yeah. Then he asked where I went to High School, and I told him where I went, in a town south of Houston. He didn't ask me anything else, so I guess I passed. He was really slick, too. He was more conversational than any other TSA agent I've encountered...it wasn't like he was questioning me.
