We're only a little more than a week away from the Deni Ute Muster, so it must be someone "crankin' it up furious" and practicising some Circle Work, with AC/DC playing Thunderstruck on the stereo.
The dust here has been pretty amazing, and only arrived about 6 hours after Tony's post said it was in Yass, so the winds can't have been that strong! The place looks like Pompeii today.
