I recently watched a documentary on the underground town, Coober Pedy. Have you ever been there... heard of it? I was fascinated.
There's something magical about the idea of Coober Pedy, a town in the middle of South Australia, red, hot, full of Opals (it's the Opal capital of the world!), where everyone lives in caves underground called 'dug outs'. There are even churches underground!
But as well as being fascinating, this is a very valid action. It prevents the inhabitants from being too affected by the heat, as under the ground the temperature is more constant. And it is eco friendly, before the term existed. Many sci fi books I've read imply that in the future we should all be living underground.
Though I've obviously heard of it, and I've read books like Fire in the Stone by Colin Thiele (I'd recommend it!) I have not been there. Why, you might say, looking at the map. Don't you live in South Australia?
I do indeed. But it is 850 kilometres away, or over 9 hours drive. One day I'll go. How about you?
