Woes with Wavering Weather

Last night for astronomy we had planned to do the oh so boring time and diurnal motion lab. Basically, the purpose is to bore the brains out of the students while hoping they learn something about the movement of the vernal and autumnal equinoxes. We did this lab because it was supposed to be cloudy and this is typically an indoor activity and procedure. Had there been clear skies, we would have as Pat said "done the moon". Regardless, we spent the three hours allotted to astronomy lab in the fifth floor hallway of the physics building. After the last student left at 11:50, we were free to go. Upon exiting the building I noticed that there was not a cloud in the sky and there hadn't been one since way earlier in the evening. This has happened almost every week for this class. Not once has the weather been nice during the day, then nice at night too. Either we plan a good lab and it gets ruined by the low visibility, or we plan a bad lab and there are suddenly clear skies! We can't win! Clouds just need to make a decision and stick to it. There should be none of this uncertainty business. In conclusion, this was sort of a round about way of saying it but, I hate clouds.
