My elementary school had a two storey tall jungle gym. Climb up to the top and if you fell down, you would die. And several kids were on that thing just having a grand old time. The teachers didn't seem to mind, either. Heck, I remember having a straight slide that was taller than the one pictured in this article. This nanny state we are living in is designed to make sissys out of men. Let the kids throw other kids down, it will only make them stronger. Goodness. Heck, in the bathrooms the urinals were as tall as your head, floor to chest height. We'd begin pissing and then back up to see who could shoot the farthest. Was a great time until the teacher came and and yelled "What's taking you so long!" Talk about a stream of piss being cut off in mid flight. The janitors sure had a mess to clean up. Be we were kids and that's what kids do. Push the limits until an adult said differently.
