I just bought a ticket for a quick visit to Washington DC in a few weeks and I am wondering if I should carry my Paddy or carry a different purse for the trip? Specifically, has anyone had any trouble going through airport security with a Paddington? Does the lock and key set off alarms? Does it offend the TSA in any way? ('Cause it does seem to me that you could, really, KILL someone by swinging that heavy lock at their head!) TIA!
