Yup. That's another thing. Have *everything* for departure and at

they say go they mean go. When you pull into place you are expected to
be going in just seconds.

Which is a good idea for any busy airport. I can not understand people
who sit there and diddle their DG, transponder, whatever for two minutes
after being cleared for takeoff (at controlled fields) or after they
pull on to the runway at uncontrolled fields. About the only thing
I do while pulling on the runway is hit the strobes (if at night).
