Rutgers Gardens hosted its annual Fall Festival over the weekend to help raise funds for the 180-acre public garden. Bruce Crawford, director of Rutgers Gardens, said the festival is a fun day out intended to serve as a fundraiser and community awareness event. “As long as the gardens have been here, there are still a number of families who don’t know we exist,” he said. “There’s nothing out front that screams ‘Rutgers Gardens.'”…The preserve, which opened in 1922, is tucked away off Ryders Lane between New Brunswick and East Brunswick.
