I know the feeling. Got into sub freezing weather for almost the entire last week. That doesn't normally happen here in Seattle. My sample jars began clouding at around 32F, and the next morning at 19F they were nearly solid. Cut my tank to around B60 with pump diesel and had the same experience with the sticker shock. Not used to that! I just told myself that it's a good thing I don't have to do that very often. Come to think about it, the end of November is the last batch I made too!
