I'm 74, and I am in the middle of New York State. I also have about 400 taps (this year and the previous 2). I am the old guy, I get help from my 7 yr younger brother in law and one of my sons (and his significant other) at times. We try to keep it fun.
The most pails I ever did was about 120. Now all of my taps are on tubing and high vacuum and the sap all flows to the sugarhouse. My high vacuum (26-27") is by using a vacuum pump that is likely older than I am, it is a BB4, a piston dairy pump by Babson Bros, who later became Alamo.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
