Genghis,
Not quite the same but your story took me straight back to the one & only time I've been to the NBAA gathering. We arrived in the owner's XLS, did as instructed by the FBO & put the sheet of coloured paper notifying which day we were leaving in the window etc. We were only staying for 36hrs. Due to depart at 1pm, fortunately we decided to head to the airport by 9am just to make sure everything was ok. Couldn't find the plane & after much searching, eventually found it buried behind more than 35 much larger corporate jets. It took quite some negotiating to get it out of there, and we eventually left about 2hrs later than planned.
Kev - how about making use of one of these
