Memorial Day is fast approaching. And with it are town and city parades, complete with military flyovers, all scheduled for the time of each parade. Obviously, some parades won’t get a flyover but (and I know I’ve asked this question before) those that do offer an opportunity to monitor the aviation chatter as the aircraft transition from one parade to another. I’m looking for those frequencies that may be used, which can change from year to year. Thanks in advance.
