     THE first night in Yosemite had been awful. I hadn't been able to sleep and I was stuck in a too small

tent with my wife and two kids. "Things haven't worked out," I said to myself. But, like so many other

things I complain before my morning coffee, this one was ridiculously off-key. Things weren't bad;

they were good.

     A hundred yards(91 meters) away was Summit Lake, with its wonderful early morning mists (薄雾)

shimmering (闪烁微光)off the water. A couple of miles to the southwest was the base of the Lassen

Peak Trail. The base was 8,000 feet (2,400 meters) above sea level, huge snow banks dotting (点缀)

the place even in mid August. It was beautiful. We fired up the camp stove, got out our cold boxes from

the heavy metal locker(储物柜),fired up some bacon, cut open some bread, and boiled up a cup of coffee.

     Half an hour later, my 6-year-old daughter and I were in the parking lot of the Lassen Peak Trail,

getting ready to hike. We wouldn't make it all the way- young legs get pretty tired on a steep mountain

path, but it didn't matter. We would see great views spread out below us, the volcanic ash (火山灰) that

layered on the earth turning the melting snow a mysterious pink as the sun struck it.

     Later, on the hike, I felt stupid about my morning complaints. Everything had been worthwhile. It gave me enormous satisfaction to see my daughter so excited about the view from the mountain.

     Yes, camping is uncomfortable. But there's also something wonderful about being so close to nature.

Just as importantly, there's something about getting young children out of their increasingly

technology-filled comfort zones and forcing them to encounter the non-cyber (没有网络的)world

around them.

     We lose something when we spend all our time cocooned (束缚) inside a carefully constructed

modernity, when read about daily affronts (冒犯) to the environment, yet don't fully realize what is at risk,

removed as we are from nature. It's a good thing to reconnect every so often with the Great

Outdoors.
