I remember walking around General Mitchell Int'l Airport in Milwaukee the day we left with our robot's controls as my carry on. I got some very strange looks and lots of questions at security, but they let it through and I wasn't even searched. Right after I walked through, our human player was behind me, and he got the whole shoes off search, and I walked on down to the gate with my joysticks
.
Also another funny one is that on the way back, we carried on the 2 "FIRST Robotics Championship" signs that we have permanently borrowed from the Reliant Arena Complex, well on Sunday afternoon before we left we took off the "hip" on the signs so they said "FIRST Robotics Champions" and we carried them around the Houston airport on onto our flight. Well the flight crew saw them and as we started out final descent into Milwaukee the captain came on and said "I hear we have some champions aboard..." and we got this round of applause from the jet, it was classic.
