What is the American state of mind? Literally boundless. The beckoning of the perpetual road trip. The shaking off of fetters. American freedom has been the freedom to move beyond the cramping parochialism of the Old World. Now, that's all come grinding to a halt. Americans are hurting. Americans are hurting today. America has run out of infinity. When it comes to the global debate on climate change, our country is struggling just to stay relevant. Hard times have stalled the American optimism that's always been the heartbeat of its history. The American West has been a symbol of opportunity, growth, prosperity and freedom, discovered as an unending Eden that would eternally provide for this nation. The determination to move on, to engineer a profit out of dirt, be it a harvest, a ranch or a city is the urge that's made America the land of plenty. Understandably, not many people are going to stand up and say, "Stop." But some Americans have been brave enough to say, "We have limits." If we succumb to a dream world, then we will wake up to a nightmare.
