This was the opening video for Hidden Earth 2018, the UK's national caving conference.
When I was asked to produce the opening film I wanted to try something different, something really different, different from anything that had gone before. I know that I could have gone for a safe low risk option and produced a beautifully filmed and narrated caving documentary, but regular viewers of my videos will know that this wasn't for me.
It has proved to be a 'marmite' video which people either love or hate. What about you?
