Well folks, I don't know what you trees are doing, but mine are in a sap tsunami right now. I have received 60 gallons of sap in the last 5 hours. The forecast calls for temperatures to continue to rise through tomorrow afternoon, so I imagine this is going to peter out at some point, but its pretty awesome right now. My 1" main line is 1/2 full and constant...nvr seen so much sap in the pipe before.
