It starts here, in my back yard, towards the end of winter. My neighbor and his son-in-law come and attach the tubing to the trees.
Then they wait and hope for correct weather conditions. Nights must be cold and days warm for the sap to run.
Shortly after the line is put up, the neighbors drop by to check it out.
When the forecast looks promising, the men return and drill holes in the trees. They seem to know just where on the tree to drill.
Then they insert the taps which drain the sap into the tubing.
If you look closely at the tubing, you can see the sap running through, unfortunately that doesn't show in the photos. It travels thru the tubing to the big container at the bottom of the hill.
