Slightly OT:
I had a customs or border patrol agent upon returning from PVR demand to know why a few of the items in my suitcase were damp. I answered that I had went swimming in the morning before leaving for the airport in the afternoon and things hadn't dried. He was not satisfied, and I was subject to an invasive secondary screening of my person and my luggage. This WAS 10/2001, so I am guessing they were still on pretty high alert.
