Everyone, remember that this was a brutally cold winter, so if the trees aren't going much yet, they probably are still froze up. FWIW I have only 4 going spiles out of my 18 spiles here at home, nothing so far from the virgin bush of only 6 spiles. I will probably collect that grand total of about 1l sap from my home trees later today and let it evaporate down to about 1cup on the woodstove, just to get it out of the way.
