You have to be on the ball in some areas.
Like around Gatton Qld flying into Caloundra over the Somerset dam wall. I have to monitor 127.65 Toowoomba, watts Bridge. 127.3, Kilroy 127.6 and Caloundra/Cabooltcha 118.8
Easy to miss inbound calls, obviously transmit my position, heading, height etc to the near strips.
There are probably plenty of other areas where planing your calls are most important.
