Put on your walking shoes Saturday, May 1, from 10 am – 12 noon, and join The Esplanade Association’s spring walk, guided by Karl Haglund, noted historian and author of Inventing the Charles River. Mr. Haglund, who also serves as the Department of Conservation and Recreation’s Project Manager for the New Charles River Basin, will delight you with fun facts about the Esplanade as you take in the sights and sounds of the park. Meet in front of the Hatch Shell, rain or shine. You may contact Justin Burke at 617-227-0365 for more information, or log on to www.esplanadeassociation.org.
