Green Acres, Cary

David and Beth Ferrell are the fourth generation of Ferrells to make their home on Green Acres Farm. But under the couple's stewardship, the farm has gone decidedly high tech. In the fall, when pumpkins are ripe for picking and Christmas trees are still lifting weights in preparation for winter, the farm opens its 10-acre corn maze to the public and encourages visitors to make their way through with help from a smartphone app. They can use the app to answer maze trivia and scan QR codes at various checkpoints sprinkled throughout the 2.5-mile labyrinth. Once complete, adults and youngsters alike can enjoy all the other farm attractions, such as face painting, hay rides, and corn hole.
