“But a choice made is made, it cannot be changed. Things happened as they happened. It is possible to imagine all kinds of different routes across the continent, or a better way for the government to help private industry, or maybe to have the government build and own it. But those things didn’t happen, and what did take place is grand. So we admire those who did it—even if they were far from perfect—for what they were and what they accomplished and how much each of us owes them.”
