You want sad? Howzabout making flight plans (complete with wind) for flights you have no intention of ever making, just to see if you can - good for those times you can't go flying for whatever reason, and always good practice too!
(Of course, it loses its appeal when you actually have to re-do a flightplan four or five times because the flight keeps getting cancelled for whatever reason... )
Having said that, I have a few days off work this weekend, hoping to do at least three of the four navs I have to do before the flight test... getting there slowly!
