We didn’t finish cooking.  If everything went right we would’ve finished by 4:00 PM.  It didn’t go well.  Into the woods by 6:15 AM.  Had the R/O going by 7:00 AM.   Had two batches into the milk can by 9:00 AM.  Then started feeling unwell.  Chills.  Tried to work through it but by 10:00 AM it was obvious we needed to rest.  Shutdown.  Back to the farmhouse by 10:30 AM.   By 12:30 PM feeling better, but the R/O was into its wash cycle.  Then needed to cool.  We were not able to fire up again.  We will retry in the morning.  Feeling fully recovered now.

Returned to the woods at 4:30 PM to deal with the concentrate.  Concentrate doesn’t keep well.  So we pumped back into the storage tank, then added R/O water to get back to 2° Brix.

20 overnight.  A cold northeast wind made the ground frozen hard.  36 and sunny today but the northeast wind continued most of the day.  The trees did start dripping.   Low 20s help stimulate that.  Tonight is low 20s again but warmer, low 40s, tomorrow.  The sap run should continue.
