Means maple syrup time! A friend of mine has their own sugar shack and trees tapped. I will take you on a little tour.
These are some single buckets, but mostly all tapped into a plastic pipeline that brings all the sap from the tree into the sugar house.
Close up... :)
Then the sap gets boiled - it takes about 5 hours or so for the sap to become maple syrup.
It has to freeze at night and be nice during the day for best sap running conditions. Since the forecast is for VERY warm weather this weekend - the season might be soon over.
