Uptapper,
Are your maples on a south facing hill? If yes you may get some flow this weekend however the forecast isn't great for sap flow. We need sun and 40 deg days with near 20 deg nights and low to no wind.
My sugar bush is south of foster city 10+ miles and far from pavement but if you would like to visit you'd be welcome to visit and see what we are doing. Right now we don't believe that there will be enough sap to start up the evaporator but we will be fine tuning our new sugar shack and I will answer all the questions you wish to ask.
