I think that's a really fascinating dream, Truman, especially in light of the image of short story Ennis using his dreams, letting panels slide forward (?) to stoke his day.
Can you even imagine what an enormous undertaking that would have been to Ennis - a bus trip across the country to witness the Inauguration?? I think I can imagine it though. I bet Ennis would have thought Jack would have been excited about it, so Ennis might have gone to see it in Jack's stead, turned it into a pilgrimage of sorts.
