"I was told when I grew up I could be anything I wanted: a fireman, a policeman, a doctor - even President, it seemed. And for the first time in the history of mankind, something new, called an astronaut. But like so many kids brought up on a steady diet of Westerns, I always wanted to be the avenging cowboy hero - that lone voice in the wilderness, fighting corruption and evil wherever I found it, and standing for freedom, truth and justice. And in my heart of hearts I still track the remnants of that dream wherever I go, in my endless ride into the setting sun."
