OK, a little more explanation:
Before I taxi I say "Anytown Ground Piper 123AB, Joe's Hangars with Charlie for 24R" Then before I take off I say this: "Anytown tower, Piper 123AB holding short 24R, right downwind". They respond "123AB, Anytown Tower, Runway 24R cleared for takeoff, make right traffic" And then I go on my way. Acknowledging the takeoff clearance may be the last time I talk to anybody on the ground for the entire flight, for instance if the destination is an uncontrolled airport and if like most VFR traffic, I don't choose to call up later for Flight Following.
If I do ask for clearance through some airspace later in the flight, it'll typically be like this; "Bigtown Tower, Piper 123AB, 5 miles east, request south side transition" and the response might be "123AB, Bigtown tower, transition approved as requested, at or above 2,800, Big Town altimeter 29.87"
Nobody has any idea where I'm going.
