I see this was addressed in 2004 and 2005 and briefly last year. I am looking for some assurances that one does not get to Airport Security before being told that the tripod will not be permitted on board for security reasons. Pointed scissors and screwdrivers are permitted but I am nervous about my Hakuba carbon fiber tripod and Arca Swiss ball head. Has anyone out there been told they could not bring a tripod as carry-on? I looked at the TSA website and it does not give much in the way with specifics...Thanks.
