"I just came back from Europe with an expensive instrument in tow. There was no problem carrying in on board."
Yeah, the only time I played in Europe, everyone carried their instruments, but that was pre 9/11. The only problem I had was in Germany. The customs guy asked me why I didn't play a German oboe after looking in the case.
Ha! That's pretty funny that the Customs guy knew enough about instruments - esp. oboes - to know the difference in workmanship and style. :-)
