I've forgotten who the instructor is, but the quality of instruction is
excellent, IMO. I took some notes from his techniques in case I ever
become an instructor. The instruction all takes place at one of our
favorite airports, OSH.


The instructor's name is Dave Lammers. It takes place at OSH since it's
an EAA production (the director is the student's husband). Every so
often, you can see the colored dots on the runway.
