Gave in and pulled the taps today. Trees deep in the woods look ok, but anything on the edges buds are exploding... soft maple beside my house looks like it will have leaves in the next day or two. Lines flushed out, drums washed up.... still one pot to finish. On a depressing note, I had trouble flushing a couple of my biggest lateral lines... couldn't even blow them out... and when I cut them off the main lines I found the holes on the ainline fittings completely plugged with some kind of ooze.... guess that is why I didn't have any big runs this year... half my taps couldn't get their sap into the mainline... called myself a few names and learned yet another lesson
