Kay and Dallas Muddiman are the leaseholders of Over the Road, a property located in Crooked Corner, approximately 30km north of Crookwell. The property is a dedicated wildlife sanctuary which is also used for wildlife rehabilitation. Kay and Dallas commenced leasing the Crown Land in October 2005, and it is their intent to continue leasing the property for as long as possible while keeping it a dedicated wildlife sanctuary. Over the Road adjoins the recently gazetted Gillindich Nature Reserve.
The sanctuary covers 129.5 hectares of undulating to quite steep hilly country, covered in eucalypt dominated bush and understorey in varying densities. Several water courses which only run in heavy rain are present, as well as a rain-fed natural waterhole.
