Absolutely ridiculous. Kinda makes me wonder how I got my bong through customs coming from Germany when I was underage. It was an 18" glass on glass, so nobody would be fooled. However, I went through security multiple times in the US and Europe and I think I got pretty lucky.
When I was at the customs desk in Boston, I felt like George Jung trying to smuggle keys of coke. I put my bags on the desk and he asked me if I had anything to declare. I told him no, and he said I was free to go. I was completely shocked it was that easy so I hesitated and blurted out, "that's it?" He just kinda laughed and said yeah and I walked on through the doors in the the United States. I did have a bit of a celebration fit however as soon as I walked through the doors.
