I ask, because today, I went to the local Federal District Courthouse, had my ReVoMaze on me, entered, got to security, put the maze on the tray along with my briefcase, computer, phone, keys, blood of my first child, etc ... and everything got through, except the maze. The response? "Sir, what is this?" "It's a puzzle." "What is the objective?" "To remove the center." "Then remove the center for us." "But, I don't know the solution yet." "Sir, it has a removable center, it is obviously hollow to some extent, and the x-ray shows it as being just a black, shielded cylinder, unless you can open it and show us what is inside it, then you cannot bring it in." "Oh...." I walked back to the office, dropped it in my desk, went back to the courthouse, and entered unhindered.
Mind you, I tried to get them to let me take a peak at the x-ray

-- So, where have you been denied entry? And has yours ever been x-rayed and shown more than just a black emptiness?
