Had a great time at Coober Pedy. Visited underground opal stores and an underground bar. Amazing construction. Also went noodling for opals  in big piles of dirt but didn’t find any. The weather has been kind, not hot but not too cold. There was no water available at the caravan park and showers cost 20c per 3 minutes. We bought water in the town to top up the van tanks. There was a set up similar to a petrol station but it only sold water. You put coins in the slot to get the water. There were a few other vans there getting water.
