If I am not mistaken, Tom, the A/F Directories already list the "unicom" freq to use when the tower happens to be closed. When published, they just didn't foresee permanent closures en masse. What will make this more confusing as to which towers are closed and when, is that the FAA is going to invite local communities to opt to pay to keep the towers open at their local airports. I guess we'll just have to rely on the NOTAMS. ==== Ralph
