Typically, when someone in this group writes a quiz, they base the questions on what they think is interesting.

I'd like to try something different, and give the people what they want. I have North American OAGs from Oct 1964, Sep 1972, and Jul 1977. I'd like to invite you to choose an airport you're interested in, and an OAG you'd like me to refer to, and I'll put together a few questions based on your airport / OAG combination. Obviously, there will be more questions if you choose an airport that has several airlines serving it, than if you choose an airport like Chadron, Nebraska or Harrison, Arkansas that has limited air service.

The first three people who respond will have quizzes based on what they think is interesting. Because of my remodeling work, my OAGs won't be accessible for several weeks, but this will give you something to look forward to this fall.
