Also fun: Mexican playgrounds. I am of the firm belief that kids are meant to get hurt. That's how they learn. And the introduction of lawyers in to the situation is just less fun for everyone. When I was a kid we had a great playground: merry-go-round, teeter-totter, rickety slide. Of course, my brother broke his collar bone at the tender age of one, but he got better. No lawsuits there.
As American playgrounds are becoming increasingly sanitized (guard rails, plastic anti-bacterial coatings, the replacement of concrete and sand with wood chips), I yearn for the real playgrounds. The ones that kids like. And that is why, as an overgrown kid, I have found Mexico to be an utter joy.
