I ran my lines Friday, put in 36 taps (mix of buckets and tube) since then. Still have 64 to go, but I should have most in by mid week. Not at drop of sap yet... it was +1 yesterday and +2 today but it only hit that for an hour or so around noon.
2014 - 6 buckets, 4 coffee cans and a propane burner - almost 40L of sap and 1.6L of syrup
2015 - 103 taps on gravity. Homemade oil tank arch and a Smoky Lake 2' X 5' hybrid. - 2.66 gallons of syrup
2016 - 101 taps, 550 gallons of sap, ~10 gallons of syrup all dark.
2017 - 138 taps, 225 gallons of sap, 5.55 gallons of dark syrup, still procrastinating on the vac.
2018 - ~150 taps, I lost track of the sap it was incredible!, over 20 gal of syrup, all dark.
