I am really not worried about US customs -- my concern is the even bigger clowns known as the TSA.
FYI, the Sheesha passed through 2 Egyptian X-rays, one manual Egyptian search and an Austrian X-ray, so far.
BTW, is there any limit on how much Sheesha tobacco one technically can bring into the US? I looked at the US customs website, horrible piece of work, and the only specific mention is regarding 200 cigs and 100 cigars.
