Kids playing out.
Hopscotch grids chalked everywhere on the pavements.
All the dads went out to work, all the mums stayed at home and did housewife things.
There was a grown-ups 'eyes and ears' network, and children mostly behaved when they were outside, because they knew if they didn't, their parents would find out. There was very little antisocial behaviour. The unspoken threat of "Wait till your father gets home" was a deterrent.
'Best Garden' competitions run by the local council and heaavily supported by many residents, with hundreds of gardens all filled with neat rows of bedding plants.
The children all went to the nearest school to their house, and walked there and back, and by about the age of 7, unaccompanied.
We all knew where not to go, and would avoid such places as the house with 'the witch lady', or the 'weirdo in the bushes'.
