The differences are about how we are all over governed now in every parts of our lives. The rules for CG's now are absolutely ridiculous.
Back in the good "ole days', there were never strangers as we warn our kids of now in the parks, or so it felt, and a neighbouring RVer if saw your child was in danger or being bad, could gently grab him, or reason with him and explain something. Nowadays, you are afraid to say or do anything with others kids.
As for being really out in the boonies today with a child over the age of 5 it seems, you better have good internet connection or else your vacation could be murder. LOL That in and of itself has changed everything we knew as good and wholesome years ago growing up. We'd call back home to let them know we'd arrived OK from a pay phone nearby, and maybe once more during our whole vacation max = that was about as connected we ever were, and wasn't it fabulous?
