I find I agree with Lead and Dick here. Less unnecessary yap the better.
This coming Sunday will be a good case in point at the Jamestown airshow and fly in. Can you imagine the chaos that will occur if every VFR aircraft makes a departure report. Not only will it clog the airways for important calls but in any case nobody can possible keep track of dozens of aircraft taking off line astern.
You don't fly with your lip,so keep it shut unless really necessary and get your eyes out of the cockpit.
