When seesaws and tall slides and other perils were disappearing from New York's playgrounds, Henry Stern drew a line in the sandbox. As the city's parks commissioner in the 1990s, he issued an edict concerning the 10-foot-high jungle gym near his childhood home in northern Manhattan.
"I grew up on the monkey bars in Fort Tryon Park, and I never forgot how good it felt to get to the top of them," Mr. Stern said. "I didn't want to see that playground bowdlerized. I said that as long as I was parks commissioner, those monkey bars were going to stay."
