CRAZY weather. We tapped on Jan 15th, and it has been a struggle ever since due to warm temps. We finally had a 12 hour spell on Thursday/Friday where temps dropped into the mid twenties, and we were hoping for another run. Alas, after telling ourselves yesterday that the trees hadn't thawed yet, it's time to face the facts.... our tapholes are already drying up. 60 degrees now and I drilled a few fresh holes in some trees we didn't tap, and the sap IS running hard.... but not so much in our existing tapholes. We run tubing on shurflo vacuum, and used new check valve spouts, but I believe these crazy warm temps have dried up our trees after five weeks. Worst year we've had in a long time.
