The art of maple sugaring, a harbinger of spring, will be featured in a series of educational programs for groups and the public at Washington Crossing State Park in Mercer and Hunterdon counties from the middle of this month through early March. The park offers maple sugaring demonstrations with schools, scouting groups, clubs and community groups. The demonstrations provide an introduction to tapping trees, maple sugar processing, tree identification and folklore. The park also offers public demonstrations during the first two weekends of March. Registration is required for both programs. Read More.
