> The tables are behind the gates of the park’s Emerson Playground, which the signs in question state is off limits to adults unaccompanied by minors. I keep rolling this around in my mind. It makes sense but at the some time it doesn't make sense at all. I'm sure it's intended to keep people from kidnapping kids or adults from destroying equipment but I fail to see how it would even be remotely effective at that.
Not a good job at that - the vast majority of kidnappings (or hell, cases of child abuse in general) are done by people known to the family.
The creepy stranger who will swoop in when you turn your back and kidnap your child is 99% a figment of one's imagination.
