Its been years since I ventured out to Hartwood Acres but I can assure you I will not allow it to happen again.. Not only is the property and estate a great place to visit for guided tours Hartwood Mansion also features different teas and social events all year round. For instance, I attended a Great Gatsby Lawn Garden Party today and the event featured live music, food, drinks, lawn games, a vintage car display, tours of the mansion and plenty of time to socialize. Today's event was held in hopes that the proceeds will be used to help repair and restore the Steinway piano displayed inside the mansion.
