Heading back to Wisconsin on Saturday. We are going to start tapping. Saturday, Sunday and Monday look to be nice days, but its not certain the sap will flow. Its been cold. And the trees may not be up to sap flow yet. Last year we tapped on March 9, which was quite late. The 10 day forecast is for more cold. About 27 for highs, which is too cold for sap flow. But the sap has to flow some time because the trees need it to produce leaves. So we will tap and be ready for whatever nature gives us.
