You were parked in the employee parking lot of the PHI in Galveston, TX. I would of tracked you down but I was up for 18hrs at that point and had a 5 hr drive. Not to mention a horrible night of work.
I'm betting they aren't on any of the boards or someone would have talked them into taking the factory step tubes off. Maybe leave a note under their wiper if you see it next time you fly out.
