Dr. Patterson would be proud of me...
Mid-term, each test has a code, several images of clouds are put up on the screen, depending on the code you have you identiy a particular image as to what it is...
I get a tree line with white sky...
what the hell was that?
Passed the exam, but never did find out what I was supposed to identify...
But once in fact did see (with Dr Patterson as it turns out), a whole bunch of lenticular clouds approaching like an armada of flying saucers...and of course we were doing a prescribed burn with the class in a game preserve...needless to say, class got out early...
