I worked as a caving instructor in the Peak district (Hollowford centre, Castleton) during the 1970s. Is this the Jackpot of memory? There were two pitches in a 'waterfall', and when the delegates said are we going to get wet, all I could say was 'Yes.' Fond memories. I told them to keep the fall of water between their legs and bounce on either side of the water. My favourite pot was giants hole. Should say, thank you so much for posting.
