Gregory and Andrew took a trip to Coober Pedy to go noodling (this what you call digging in the white dirt looking for opals). It was very hot and they didn't find any opal, but they had lots of fun.
On the way home they stopped to look at one of the huge salt lakes - this one is called Lake Hart. They decided to walk out to the middle of it. They walked for ages and still don't think they got halfway. I wonder how they knew which way was back to the car??? Probably a good thing I wasn't there!!!
Out in the middle somewhere they came across the remains of a tree. That was all they found besides lots of flat white salty ground!!
