Ken Yuszkus/Staff photo: Wenham: Gary Johnson collects sap from the buckets on the maple trees at Cedar Pond Area in Wenham before taking the buckets off the trees for the season. The cold winter with not many warm days had a negative effect on the volume of maple sap collected locally. Gary works for the Ipswich River Wildlife Sanctuary where they will still keep some buckets on the treees for a while longer.
