I will fly more this year than I have ever flown in my life. Thank goodness ticket prices are relatively low now. But aside from the expense and general hassle of schlepping to and from airports, I love looking out the window of an airplane in flight. The experience of surveying the rough texture of the earth from 30,000 feet makes me reflect on mankind's ingenuity. Our ancestors looked up, saw the birds, hatched a dream and made it happen. What drive it took so that we could see what the topside of cumulus clouds look like firsthand.
