Found a couple of squirrel chews in one line which resulted in icing in the mainline. This was plaguing us for the last week or so and finally had a chance to walk some of the lines last night. Our vacuum was staying just shy of 26" so it was a smaller leak, but enough to freeze. I hope to find some time later tonight to walk more lines. We found three taps to add which we left out of the sap lines when I replaced them quickly for a repair.
Sap is finally flowing decent around here. Still quite a bit of snow in the woods. We are at 15 gallons (last three years were were around 80 gallons now) of syrup so far and hopefully will still get close to 100 gallons of syrup.
