Take a cue on outdoor living from childhood. As children, we practically lived outside, bleached blond and freckled. And even now, when it comes to summertime, we can't help getting all nostalgic. Many of us living here in the city grew up elsewhere. Many others are born-and-bred New Yorkers. We grew up in a rural area where summer outdoor living meant fort-building in the woods and slippery rocks in the bottoms of streams.
