Did you ever see the back of Mt. Rushmore?
If you could add someone to Mt. Rushmore, who would you add?
General Patton.
Mr. Rogers ...
Have to agree with Angela ! Ole Blood and Guts ! Patton !
FDR.
Led the US out of the worldwide depression and through the worst War in history; re-elected 3 times; was President while Mt Rushmore was being sculpted.
Martin Luther King, Jr.
I'm with Zee. FDR stands out among modern presidents and a non-president would be out of keeping with the site.
