Bring it on. I travel with a collapsible hiking stick (monopod) which has a camera screw on it. I have never even gotten a second glance. Nowadays, carrying a projector in my laptop bag always seems to get me a trip to the ETD table. I keep my head down and don't speak to the screener, in hopes that they will just swab my stuff and let me split. One of the zealots just about caused me to miss a flight, when they took everything out, and then insisted I couldn't touch my own property to put it back in the bag.

Bas#$%$#rds.
