Whilst staying at my friends daughters home up north, we set aside 
  a weekend to visit the Karijini national park. This is about 300 kilometres 
  into the outback, and takes a fair while to get to since a considerable part 
  of the route is undertaken on dirt roads. As we were using a Toyota 4x4 landcruiser 
  this didn't present a problem, so we set off late Friday afternoon as the sun 
  was going down. Of course this meant we would be arriving after dark, so we 
  had to keep a very beady eye out for kangaroo's straying into our path. (They 
  just love to sit there in the middle of the road forcing you to take violent 
  avoiding action.) 
  After we had located a suitable place within the park to set up camp, one of 
  my first priorities was to identify where the nearest 'bush' toilet was. To 
  the uninitiated, a 'bush' toilet is simply a deep hole in the ground with a 
  basic loo seat precariously hovering above it. If you're lucky there may also 
  be walls surrounding it for a modicum of privacy. Flies come as standard but 
  doors apparently are optional extras. After stumbling around in the dark for 
  a few minutes, I managed to track down our local convenience. Not finding a 
  door, I reasoned that if I stood my torch in the entrance facing outwards and 
  whistled loudly this would ensure that any other potential customers would wait 
  their turn. Focussing my attention on the seat, I knew that the principle rule 
  for these outdoor loo's is like having a fear of heights...Don't look down!!! 
  But...I just couldn't resist it, because out of the corner of my eye I'd seen 
  something moving. Something was a bit of an understatement. Some-things was 
  a more accurate description. Crawling up the side of the porcelain, and disappearing 
  down into the bowels of the earth was a seemingly never ending stream of cockroaches, 
  big buggers too. Oh yuk!!! Not fancying a plague of creepy crawlys erupting 
  over my butt as I squatted down, I picked up a bottle of disinfectant and sent 
  a tidal wave down over them. Roughly calculating I had about 2 minutes before 
  they shook themselves off, regrouped and mounted a retaliatory strike, I hovered 
  over the pan in the darkness whistling my head off and gave them what for. I 
  really showed them who was boss and what I thought of their social activities, 
  I can tell you. It's a very odd feeling using a loo with no door, one feels 
  very exposed and vulnerable with your trousers around your ankles knowing that 
  at any moment someone else might walk in on you. Certainly focuses the mind 
  into getting on with what you're doing as quickly as possible. 
  When I returned to our tent site, I informed my friend's daughter of the loo 
  direction, and mentioned the lack of a door. Carrying a sack of torches with 
  her, she ambled off to carry out her toiletary needs. A few minutes later she 
  returned, laughing her head off. 
  "You know you said there was no door" she exclaimed "well you 
  must have read that big sign on the front as you walked in." 
  "Yes, so what?" 
  "You know, the one that explained all about the site, and where to go, 
  and what to do. " 
  "Yeah, yeah, what about it?" 
  "Well, that was the door. Didn't you notice it had hinges?" 
  OOPS!!! ......................... Who's an extrovert?
