Hi Jack,
There must have been a lot of people with veggie gardens in those days, now if somebody has a veggie patch it is a bit of an oddity. I guess the supermarket ease of getting them had an impact. House blocks now do not allow for veggie patch and as people die off in the inner suburbs that had big yards are now snapped up to have units built on them, or they have one big ugly monolith built on them from fence to fence and any remaining area covered in concrete
