A real old police box in Scotland - "Let the TARDIS die. Just let this old box gather dust. No one can open it, no one will even notice it. Let it become a strange little thing standing on a street corner. And over the years, the world will move on, and the box will be buried. And if you want to remember me, then you can do one thing. That's all, one thing. Have a good life. Do that for me, Rose. Have a fantastic life."
