Perhaps you could say that mountaineers are driven by ego or our competitiveness, but there's a lot more to it than that. Whether it's a huge face in the Himalaya or some crag in the woods behind your house, exploration offers us a unique perspective on the world that you can't really find anywhere else.

Specifically choose not to take a GPS. Just create a challenge. You can climb Everest or walk across Antarctica with minimal gear and still have that sense of adventure. But in terms of exploration, Google Earth has this world mapped down to the square foot.

It's our human nature to explore. Tens of thousands of years ago, our species walked out of Africa, traveling far and wide across the entire planet, from the Arctic to the tip of Tierra Del Fuego, making us the most geographically diversified species on Earth.

The mountains are a demanding, cold place, and they don't allow for mistakes.

I never played music, but it's an important thing ... the studying, the inspiration.

I believe history will come to view 9/11 as an event on par with November 22, 1963, the date on which John F. Kennedy was murdered, cutting short a presidency that was growing ever more promising. Dreams died that day in Dallas; it is easy to imagine the 1960s turning out rather differently had President Kennedy lived.

War is wrong. Conscription for war is inconsistent with freedom of conscience, which is not merely the right to believe but to act on the degree of truth that one receives, to follow a vocation which is God-inspired and God-directed.

Music is everywhere and in everything! I draw my inspiration from the day to day activities of my life!
