Slow start but like JeffE said, so was last year and April came and we all had our fill. Starting tomorrow and beyond the weather looks good, The snow will take a fast hit come the end of the week when we hit the 50's with that sun angle. All i can say is if it runs through the night a few times a person can get alot of sap in a week and a half. Season could be short but none of this start and stop. . . start and stop type season. Also in 2012 (the year we didn't tap) I did put one test tap with a bag on one of our bigger trees. There was hardly anything in the bag when i pulled it, so i would also say that the trees can leaf out without giving up sap.
