We can all learn something from these threads.

It takes two pilots to power up on the same frequency at the same time.

#1 Always use the frequency board even if you are the only one at the field.

#2 Use common since and common courtesy. If you go to the field where somebody was flying without their card being up, ask what frequency they were on before flying...Dugh

#3 Once I have obtained my pin and ensured that the number of pilots and the number of pins marked roughly matches. I will look up and watch the planes flying while I turn on my radio to see if any of the planes go into failsafe. Then and only then Do I fly.
