When we went to S. Africa in April, I bought a pair of crocheted slippers to wear during the long flight. I had on shoes with a metal button on each one, so I slipped them off and put the crocheted slippers on to go through the metal detector. The TSA guy nodded, and said "that's a GREAT idea". Should I assume he wouldn't think it was such a great idea this week, when we leave for Copenhagen?
