From the great sea of High Plains their presence rises like the spirit of the West, their promise of possibility and grand worthy adventure increasing on the long approach as they resolve across the big clear sky, walling the horizon as if all has led to this, the crossing point to a bigger world… It’s not a question of what you find there or whether you’ll stay—it is a crossing that, to borrow from David McCullough, enlarges the experience of being alive.
