Into the woods by 7:00 AM.  R/O running 7:20 AM to Noon.  7°Brix.  A much better day cooking using a properly calibrated hydrometer.  Nitre did not affect boiling.  Batch off of the evaporator every hour or less.  7 batches total into milk cans.  One milk can filled another with two batches.

28 overnight.  Sunny but windy.  Up to mid 30s but the wind kept it cold.  Trees starting dripping in the afternoon.  Forecast for mid-20s and 43 tomorrow.  Hoping for another sap run.

Back to the farmhouse by 3:00 PM.
