Yeah, strange list. Graceland, really?
...and the church...to be honest, I've never even heard of that church. I'm not saying it doesn't have merit, historically speaking, but not on the top 8.
And the Sears Tower...why?
I'm just not sure I see the reasoning behind their choices. Very odd.
The Grand Canyon, Yosemite...and plenty of other places are important American sites to visit.
