In the mid-1960s, Michael Nesmith was writing songs and working the Los Angeles club scene when someone showed him an ad: A new TV show was looking for people to audition. He did — and the next thing he knew, he was a Monkee.

It is April Fools Day 2011 and Jimmy Chin, the renowned adventure photographer and filmmaker, is shooting a couple of professional snowboarders in the Teton Range in Wyoming. This is one of the first really warm days of the spring season and so there is a lot of action in the snowpack.

After college, I spent some years wandering on the cheap around South America, ending up teaching English in Rio de Janeiro. Eventually, I left Rio and headed to northeast Brazil meeting up with an old girlfriend who flew in from the U.S. We had plans to continue on to Belem at the mouth of the Amazon and then travel the length of the river to Colombia.

But everything fell apart very quickly. First, while camping with her on a beach, my passport and all my hard-earned cash from Rio were stolen. Next, I came down with hepatitis and was incapacitated for a month.

On a recent day, just west of Kabul — where the city's sooty sky gives way to fresher air — Abdul Sadiq coaches four young members of the Afghan National Cycling Federation. They're working on their riding technique while dodging the free-form traffic.
