A whole host of things come to mind...
"Just what kind of insurance policy must the city have on this park?"
"How big are we talking here?"
"Numbers? I mean, has there been a census?"
"Where's the nearest emergency room?"
"Does anyone else think this is a really, REALLY, monumentally bad idea?"
These things and lots, LOTS more run through the mind of a mama when she sees this sign, not 20 yards from a playground, with nary a fence post between:
My boy though, my boy who can now read, has only this to say, "Wow. Too bad nobody taught the ducks to read."
Best case for literacy I ever heard.
