Every third Saturday of the month, the Rose F. Kennedy Greenway Conservancy invites families, adventurists, history-buffs, and anyone interested in getting to know the Greenway to join them for free thematic treasure hunts on the Greenway. Each hunt will focus on one of the four Greenway parks, the neighborhood surrounding the park, and its unique characteristics. On September 19th we explore the North End Parks and neighborhood. This is an all ages event. Rain or shine. For a map and more information, log on to www.rosekennedygreenway.org, or www.hellogreenway.org.
