Drove out of Mount Gambier for a bit to come across the Umpherston Sinkhole.  Bees are active here.  It is an unbelievable sight.  A large hole in the ground looking like a cave and when you walk down steps to the garden below you find tree ferns, green leafy bushes, vines, hydraganaes,etc.  The grounds surrounding it are well kept and the forestry is next door.  There are lovely shady areas so sit and picnic under. Left Mount Gambier bound for Casterton. Sign says: Don't privatize South Australian Forests.  Glenburnie has a racecourse.  Country is very dry.
