>I didn't watch it, but I understand that NT insisted that it was scripted in that a character state that cycling was an activity that wasn't allowed on Avebury.<

Really? I must have missed that bit but I think it's called a cop-out clause, as in let's show a couple of dozen people scrambling up Silbury Hill and then let's have one of them say, "You know, we really shouldn't be doing this." (Tony Blair's grin and round spherical objects spring to mind).

>Out of interest, how much money do you contribute to Avebury's upkeep?<

Excuse me? 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?
