Well, duh...

Barack Obama visited Mount Rushmore last Friday, his first-ever visit to the South Dakota monument. Here’s a bit from AP’s report:

[Obama] did express curiosity about the filming of a chase scene in North by Northwest, Alfred Hitchcock’s 1959 classic starring Cary Grant and Eva Marie Saint that included a death-defying scramble over Rushmore’s presidential faces.

“How did they get up there in the first place?” he asked ranger Wesley Jensen.

“They didn’t. It was a movie set,” Jensen told him.
