The membrane on the RO is plugged just about solid and it took all day to get my sap to 3%. The wood pile is gone and one of the tires on the sap trailer won't hold air long enough to make it down to the tank and back without adding air. So even though I still had sap coming in I reluctantly turned off the vacuum pump and called it a season.

A great season it was though. I did my last boil last night and made more fancy. I didn't adjust the density and filter it yet so I don't know how much. I still have to finish what is in the evaporator too. I should be in the 280 range when all is done. That is more than 100 gallons more than my previous record of 162 gallons.

The worst part of the season, the clean up, starts today. Boiling the contents of the evaporator in the finisher and getting the membrane out of the RO are the top priorities. Then I will pull the buckets and move on to the tubing.
