There is a wonderful parlor game called Humiliation. The goal of the game is to name something that you haven’t done that everybody else in the room has done. To win you have to embarrass yourself, hence the name: Humiliation. For example, at a social gathering of English professors, admitting that you have never read Hamlet would glean you a lot of points--one for each person who had read Hamlet (and you might also earn the disdain of your colleagues). At a Fraternity party you could score big points by confessing to your Brothers that you never got drunk and threw up.

So, in context of Flyertalk, what rudimentary travel skill or feat do you lack that everybody else has accomplished?
