Connecticut Audubon Society is opening a new preserve in Sherman, year-round. The grand opening of Deer Pond Farm is being held today. The preserve has been open only for guided walks in limited areas and at limited times. But now the public will be able to explore more than 400 acres of the preserve all year long. 10 miles of trails will be open from dawn-to-dusk. As part of the grand opening festivities, a bird walk will be held at 8am, a 10am ribbon cutting and a raptor show by Skyhunters in Flight at 10:30.
