MG is right.
Some of the best times I have had flying is instructing on a summer day over the Sussex countryside with the windows open ALL THE WAY!!! (C152).
Then the fun of watching the apprehension/horror on peoples faces as they sit in their car and see the aforementioned aircraft on a glide approach trying to take the ariel of the roof of the aforementioned car in desperation to land somewhere near the numbers. Only one student managed it. Oh how we (not the people in the car) laughed.
