Met a family whilst camping at Quorn, SA. They came from a sheep property out of Perth. We were enroute there as part of our 'big trip'.
We hired a car, & drove to their property at Pengilly. It was lovely to have a 'tour' around, & of course, fresh scones & a hot 'cuppa' were had! Fabulous!
This was back in the late '70's, & he was using methane gas from his piggery as power. It was forward thinking in those days.
A most enjoyable day trip!
