We flew to Durham to celebrate our sons graduation at Duke (pics in show us your pics). At Ithaca Airport, they pulled my bag after passing it through the x-ray machine three times. My kilt pin was causing the bother. I explained, but they unpacked the bag, took out the kilt and had a good look. We had a nice chat and I said, "good job I did not have a sgian dubh with me." The airport official said it would have been OK as checked luggage but not as hand luggage. The kilt pin (lethal 3 inch pin) was OK.
