Sap is flowing although not as well as you would expect with a 45 degree day yesterday. Still snow and lots of ice in the woods so maybe thats keeping the sap at bay. Lots of tubing leaks this year, not sure if its just the tubing getting older or a bad squirrel year but it will take some time to find them all. Sp-22 maintaining 20+ inches of vacuum but deadheaded they are 24-25 at releaser.
