I once read an account by a journalist who left her purse with all her ID and tickets in the cab to the airport. Fortunately, she had taken pictures of everything with her phone, and although it was a nuisance, she got home on schedule.I once inadvertently packed my driver’s license in my checked baggage in San Francisco. They just asked for a bunch of other identifying documents (Credit Card, Medical Insurance Card and such) and then just let me through. Just had to wait for a supervisor to process the id verification. But no additional pat down or anything.
Since then I keep a second acceptable Id in my wallet - either the Global Entry Card or the Passport Card.
I really should take a pictures of my IDs, etc. Maybe I'll do it now, while the Cardinal is stuck outside the station at Hinton and a CSX coal train is blocking my view of the New River. A pity, we had been on schedule up to this point. Hope there's enough padding to get me to Baltimore on time.
