Across three different homes, my backyards have generally had a play set with a slide. Because my children often played on these slides and monkey bars with just their siblings or a handful of friends, they developed habits that might count as a bit antisocial on a packed public playground: My kids might climb up a slide that some other kids were about to come down, or they might take their time going down the slide, inconveniencing everyone behind them.
Also, these guidelines applied only in certain circumstances. If we were the only family on the jungle gym, they could be more anarchic in their play. If there were no very young kids climbing, and everyone was up for it, a chaotic game could develop with kids going up and down the same slides simultaneously, crashing into one another.
The folks in charge of one playground in my county see it differently, though. Lenore Skenazy at Reason magazine reports from Fairfax County, Virginia. The rules at the playground include, but are not limited to: But some of these rules are efforts to codify the reasonable playground norms that kids have to learn, and this is the more interesting part for me.
