As a child born in the 50's I was interested to see some of the old footage of Sydney. Brought back fond memories of the city in those days. Double-decker buses, no traffic lights on most city streets, police directing pedestrians, sailing boats on the lovely harbour, etc.
One day in the late 50's I was in the centre of Sydney with my mother and 2 younger brothers, when I wondered away and got lost from them. No problems for a 5 year old; I decided if I couldn't locate them, I may as well walk home (10 km) as I knew the way, so I did.
Remember waiting a few hours before they arrived home and made a fuss over me. Think mum was pretty relieved.
Wouldn't recommend doing that nowadays.
