I have just been to America on business and took the oportunity to make a few purchases at the LEGO stores there and through BrickLink and thought nothing of it. As LEGO takes a lot of space when boxed I broke all the sets down. When I got home I started building a couple of sets and to my surprise found a card mixed in with the pile of instructions saying my luggage had been searched by the TSA! The agents face must have been a picture since the bag they searched contained only a few items of dirty clothes and about 20kg of LEGO! Just a funny story I wanted to share with you guys, has anyone else experienced this with airport security?
