This year sure made up for 2012. I got 20.5 gallons of syrup from 46 trees on buckets. The biggest lesson learned was that tapping Feb 20th didn't really hurt my sap yield as far as I could tell.
2011 - 7 taps, 2 steam pans, block evaporator outside, 4gph
2012 - 32 taps, 5 steam pans (one drop tubed), block arch under lean to, 10gph
2013 - 46 taps, 5 steam pans (3 drop tubed), block arch under lean to, 18 gph
2014-2016 - Can't remember, moved and skipped a year somewhere in there
2017 - 60 taps, 2x6 pan with drop tubes, under roof (no walls), 20 gph
