I recently stumbled upon the TSA blog and was pleasantly surprised by the often amusing and unexpected posts, including a response to a video on gossip website TMZ showing Britney Spears walking through airport security carrying a Big Gulp (the blog post explained that the cup contained only ice, which is permitted under current rules). The comments are equally spirited and surprisingly numerous (the Britney post, for example, garnered more than 200 replies).

Of course, some of the posts are more practical, including this handy roundup of holiday travel tips, which explains the latest TSA guidelines regarding liquids, family lanes, food (you can carry on pie, but dips and spreads must be checked), and even snow globes. The post includes a link to a printable PDF with helpful hints for holiday travelers. Happy trails!
