The Duke Farm
The Duke Farm was home to Uncle Jesse and cousins Bo, Luke and Daisy (and Maudine the mule). In The Runaway, the farm is said to be 18 miles out of town on Mill Pond Road.
The original Duke Farm, as seen in the Georgia episodes, was a log cabin built sometime in the early- to mid-1800s. It stood at 2201 Lenora Road near Loganville, GA. A few years after the series was filmed, the cabin's owner decided to start taking it down. This process was halted when it was found that there was a preservation order on the building. As time passed, the structure became unsafe, and despite fans' attempts to save the farmhouse, it was demolished in 2011. Some parts were sold off to fans.
Like the replica Boar's Nest, the California Duke Farm was built to resemble the one in Georgia. It also moved location as the filming changed ranches. For the Reunion TV movie, the rear of Boss' house was used as the Duke Farm, despite bearing no resemblance to the building seen in the series.
