OK. Experiment over. My friend got only about 15-16 gallons of sap out of 10 small maple trees. She boiled it down and got about two pints of syrup. She says it tastes VERY good and promised to give me a taste tomorrow when I see her. She said she will definitely do it again. She learned that it goes much quicker to boil only a couple gallons at a time as boiling large quantities at a time takes a LONG time.
