Have you ever looked at the Harold E Holt Communications Station VLF towers facility, located in the north west of Western Australia, on Google Maps? 

Well you should, just for the excellent geometry the towers create. It's also a pretty amazing part of the state, I once had the pleasure of a 3 day fishing trip to nearby Coral Bay where we floated our boats between migrating whales. One of my life highlights, but that's another story...
