I can assure you that this place really does exist, in fact I have been there. And I can also assure you that no-one has bungled it up with Photoshop.
Nice picnic spot. You bring the butter, I'll bring the knife.
Good. So what is the event.
Other than an ancient volcano, not much happened in a place with names in surrounded towns like Coonamble, Gilgandra, Gulargambone, Tooraweenah and Coonabarabran. At least the last one does have an astronomy observatory. Good place to be later this year.
