Is there something I'm missing about the Bradford/Leeds connection? Is it featured in a song or book, or is there some kind of special significance to the distance between those two cities? The question seems a bit random to me.
I daresay it's basically because they are two of the biggest cities in the country but right next to each other. Although a map seems to show them as reasonably separate, when you actually go there it's very hard to tell where one ends and the other begins - at least that's how I find it.
I'm not sure how nitpicky this is, but maybe allowing just "Westminster" for the Abbey is a bit easy? There is a Westminster Cathedral as well, which is a different building and not the right answer. In fact now I think of it, there's an Agatha Christie book where working out the answer depends on knowing the difference between the Abbey and the Cathedral.
Irresistible.
