Based on what my friend from up north said yesterday, I decided to check out my sap buckets. What a shock! They were all full to the brim with frozen sap. Probably about 11 gallons worth. So I took the buckets in the house and replaced them with empties. I guess I'll be cooking syrup again tomorrow.
I really never thought the sap would run with the cold weather we've been having. I guess the warmth of the sun has a lot to do with it, too. It is welcome, though, because if the weather suddenly turns really warm, the sap run will be over.
