Yesterday we tapped 4 silver maples and we hope to tap 6 more today - I bought 10 spiles just to see how this would work. We live in southern Maryland so we won't have a long season but this week the weather is perfect - finally a reason to enjoy the cold nights! This morning the boys woke me to tell me there one soda bottle was about 3/4 full. Sure enough at 9am I collected it up and we got 76oz of sap. I don't suppose we will get more than 1 or 2 breakfasts from this, but we are learning a new skill and it still seems like ages until we can work in the garden.
