Locally, the *charge* is $25/hr. I don't know how much if any of that
the airport keeps back.

Most instructors locally don't charge for ground time, which often
doubles the time they spend with a student. When I went for an XC
flight, my instructor would drive up from MA, say 150 miles
round-trip, and sit around the airport until I got back, for no pay.

I've never understood that. Around here we even charge student pilots
on their first solo when we stand next to the runway with our handheld
radio and a camera.
