maple sapper! Our gravity system is more than dissapointing this year (our first year). From inspecting others tubing systems we seem to be set up quite nicely however we have very little slope. 250 taps and about 900 gallons of sap, so far 13 gallons of finished syrup, 1 gallon of burned syrup, and the evaporator fully sweetened. Hoping for at least one more run, we reamed out 120 taps just make sure we could take advantage of any late flow. We have only had 3 light runs, 2 medium runs, and 2 OK runs.
