A landscape, a mind set and an independence all of its own! This scene is typical of Lightning Ridge and its "suburbs". The mounds are the mullock heaps from the underground opal shafts - these open shafts litter the landscape. The car door is a street sign directing strangers to an item of interest - there are few actual street signs and the diggings stretch for kilometres throughout the landscape - with a warren of dirt tracks connecting them. It is not recommended that you stray too far into areas you don't know, the mine shafts are a danger, it's very easy to get lost and it is not a good idea to turn up unannounced on somebody's claim.
@suzanne234 We found out why they used car doors - there are old, derelict cars everywhere. And in some areas you don't even have to have a registered car - any old banger will do!! :)
