Well, everyone asks. In fact, it is just about the only thing that many people ask – what was your favourite of all the many places you have seen on your trip around the world?

Well, we have a few. Depending on who is asking, we sometimes give different places so we can add some healthy variety to the tall tales we tell. In truth though, it will be hard to beat the side of the gas crater in Darvaza where Lucy agreed to marry me.

It’s not my best video, or my best edit (or indeed my best Prodigy remix), but it gives half an idea of the grandeur of the place. The government is drilling for gas in the region to try to extinguish the crater as they think that an industrial accident still burning after 50 years is bad for the image of modern, thrusting Turkmenistan. Life is short – go while you still can.
