I was lucky enough to be a kid at the tail end of some of the old-style ways, before everyone was sue happy or worried about pedophiles.
I was in kindergarten in '89, and we still had monkey bars and those solid swinging vertical bars where two kids could climb and see who rung the bell first. In PE we had an obstacle course with a giant net that we climbed, up until about 4th or 5th grade. Our parents cut us loose and said be home at this time and nobody worried about the kids being unsupervised. Got two bucks from my mom and went to Olsen's Market in Lander WY and left with 200 pieces of penny candy...
About the time I hit middle school, ALL of that stuff was gone. Kids are worse off now in a lot of ways, but I can't with good conscious let my 6yo daughter go out of my line of sight, never know what kind of sicko could be eyeing her...sad days now.
