I just got back from a trip to Cameron Corner, Haddon Corner, Birdsville and Lake Eyre. One place in particular was an old railway bridge the Ghan used to run on outside Marree. When I stopped to take in the view there was an enormous amount of toilet paper around the base of the bridge where many many people have apparently relieved themselves.

It was a disappointing site to see. I mean pretty much most people travelling these routes carry a shovel. people just don't think. But hopefully this chaps YouTube video will get the message across.
