Please answer my question re: "Would you care to explain the reasoning behind your question and how it might be relevant to the airing on prime time television of people going up and down the ditches of a World Heritage Site on mountain bikes?"

We'll then move on to the question of 'black and white'.

Oh, by the way, a friend and I spent some £70 in the National Trust shop in Avebury over the weekend - the sign to the right of the door as you go in reads, 'Proceeds from the sale of goods at this shop go directly to the upkeep of Avebury' (or words to that effect).

Now, tell us, how much money do <i>you</i> contribute to the upkeep of Avebury?
