We agree about the distances apart - too far. NAMHO has a strong policy that underground trips must be arranged with appropriate permissions. This will obviously reduce the number of ug trips in Cornwall. I am aware that there are many possibilities of ug trips to places that we do not name , but we need to protect these sites from accidental publicity.What's the plan for underground visits? In 2020 we planned to do the underground trips in the Tamar Valley. Whilst I agreed to run this side of the conference I didn't think that having the conference based in two centres 60 miles apart was a particularly great idea.
