WWLP, March 22, 2018. For many farmers here in Massachusetts, this is the perfect time of year to collect sap and turn it into delicious maple syrup.

Through CISA, a nonprofit that stands for Community Involved in Sustaining Agriculture, we visited a local farm to see how some of our biggest pros have been churning out syrup since 1835.
