It's sure sign the temperatures are warming, when the ants and other insects visit the taps. As unappealing as some would find this, it puts a smile on my face to watch them.
We didn't gather much sap yesterday, (and no, the ants didn't drink it all). From the 12 taps the volume was about 16 gallons. Which I boiled down into six cups of dark syrup -- very tasty. I'm thinking our season has about tens days left. After which, the sap harvest will lessen, not providing enough for a boil, and the temperatures won't be cool enough to keep the sap from spoiling.
At the beginning of the seasons our collection bins are buried in snow on the shady side of the sugar shack. Now, with warmer temperatures and no snow the sap sours if not boiled daily. So far we've made four gallons. Another gallon would be nice, but I think with the current forecast, it will be a stretch.
postscript: Only gathered 6 gallons this morning. And all the taps were dry. The end is in sight.
