Across the road from me, there is a relatively new park which was carved out when the old site of the Royal Hospital for Women was 'de-mobbed' and converted into very swish apartments. The RHW was moved out to be on the same site as the Prince of Wales (PoW) Hospital at Randwick.
This park is an off-lead park from something like 4pm - 8pm. All the owners are assiduous at cleaning up after their pets. The pets entertain each other and neighbour gets to meet neighbour. There are many low-rise apartments in the vicinity, and terraces that don't have much of a yard. I often go over to quietly enjoy.
