I haven't flown since 2003, the only time post-9/11. Looks like I am missing lots of stuff I really do want to miss!
My drivers license renewal is coming up in a few months and I have been told what I need to get a "REALID" which can be used to board a plane and do some other things such as entering some federal buildings. My birth certificate is a non-certified copy, so I lack anything they will accept at the DMV to get a REALID. Probably just as well, as I don't plan to fly again for the rest of my life if I am lucky. And I can renew a regular DL by mail, saving me a trip to the dreaded DMV.
And if you need to go to a federal building? Say you are audited?
