I am a bit puzzles by this video. First I did not recognise the cave entrance. I might not have bottomed all the caves on Mendip but at least I always managed to find the entrance. Did the caver leave note of which cave he went down and what time he was expected home? I think not. Another puzzle, how did the camera man get there first? He was always the other side of a squeeze. Was there an easy way around? I recognised the cave as Goughs by the Swiss Village and the formation at the end of the show cave. If the caver got into Goughs by the back door, surely he would say where the entrance is. It would save us all ?18.00 a person to get in. I think the minimum party for caving is three people. Finally, can I recommend a battery mounted helmet and three forms of light with spares.
