Gotta say that last year's trip to Ayres Rock had a few disgusting road side stops happen....pulled up at a rest area heading to the rock itself after turning off the Stuart Hwy, there's a phone booster thingy there and we needed to contact someone, whilst the misses made a phone call I thought I'd duck into the scrub and take a whizz...didn't get 2 metres into the scrub before seeing numerous landmines laying out in the open, ended up turning around and backtracking real fast. A few days later we stopped at a different rest area on the Stuart Hwy to have lunch, thought we'd head down the back of it to get further from the highway but the toilet paper in the grass and rubbish in general put a stop to that idea, headed back to the front of rest area and pulled up beside the one and only table and chair set up there which happened to be in the dirt under a tree, misses started making lunch in the campers kitchen and I start walking around...on the other side of the table some grub had emptied thier chemical toilet into the dirt there...FFS, what goes through some people's heads to think that is a good idea. Thinking about that now, I guess it shows enforcing being self contained still won't stop the dickheads from doing the wrong thing.
