"I went for Men-an-Tol, largely because it's obvious and is the most likely to get a lot of votes."

Who says?

As much as I love the far west I would not say the Men-an-Tol is obvious..it is on a minor road and still requires a walk across uneven moorland to reach it. If we are going for obvious then it is more likely to be Lanyon Quoit or The Hurlers.

and although the Men-an-Tol is manmade it is not really a structure is it...more a setting.
