Concord’s October Farm Riverfront is a special place. Its 80 acres include more than a mile of river frontage, where the Concord River makes its great bend and turns to the north around Ball’s Hill. More than 100 years ago, noted ornithologist William Brewster purchased this land to save it from the developer’s axe, but it was not finally protected in perpetuity until 2016, when the Concord Land Conservation Trust and the Town of Concord teamed up to acquire the property with the generous support of many private donors and town and state funds.
