I can never see any reason not to call. It costs me hardly anything, takes me hardly any time, I might learn something to my advantage and every tower has always been very appreciative that I have taken the time to be polite.
Does not matter how much it costs or how time consuming it is. It is just another annoyance to do.
If GA is aiming to be some kind of
semi-real transportation there must be only necessary minimum of limitations or conditions to use an airport. PPR is one of less useful I think. One should be able to get all the infos reading NOTAMs and the website of the airport, check the weather, kick the prop and fly.
Using some farmers field is something different of course.
