Do you have much experience flying in small planes?
It can be an acquired taste
If you do and are willing to do it, no private pilot I know minds if a passenger asks them a few questions about their experience, etc., including costs.
I fly with my neighbor once a month or so and I always ask him when the last time his big ol' butt was flying as PIC.
FWIW, my experience has been that the air park folks are usually very good and conscientious.
One last thing, make sure you have arranged a way back to P.A. if Chuck Yeager turns out to be Chuck Wagon or the weather turns goofy.
