I departed SFO from new F16, old 85 yesterday morning (the first few hours of the new system) and have to say I was impressed at how cleanly they had swapped all the signage. Not only was the terminal signage perfect, with no traces of the old system, but on the pilots' guides they had even repainted the tarmac label blocks at the start of each taxi guideline lane to each gate. There must have been rehersals plus a considerable crew to do this all in a few hours.
