Flying back from Long Island today, the security guy at MacArthur airport (I’m not sure whether he was with the TSA or not) checked the expiration date on my Tennessee driver’s license. He told me that it had expired. I pointed out the extension sticker on the back, and he let me through. He told me that if the license had actually been expired, I would have had to go back to the counter, presumably to present further proof that I was indeed the person I claimed to be.
God forbid that someone fly with an expired driver’s license.
