Rosemary, I think you need to get out more.
Georges Hall to Parramatta is a mere 14kms. I feel I should tactfully point out that even 200 visits over 20 years is a pretty low excursion rate over such a short distance.
I'd like to suggest that you live dangerously and enjoy a day trip to Ultimo where you'll find interesting Victorian architecture, the weird and wonderful Chau Chak Wing building at UTS, a lovely promenade repurposed from a goods line and a museum full of fascinating artefacts. Nearby at Central Railway is Mortuary Station which is marvellous all on its own.
After all variety is the spice of life.
