Believe it or not, TSA now does in fact have its own blog, evolution of security. The TSA blogging team is doing a good job, including asking for readers to submit their own favorite TSA stories, good or bad. Check 'em out--there were 218 of them last time I was there.
They also say they plan to try to answer questions posted by readers, so if you have a burning question for them, go for it. They definitely get an A for chutzpah.
