I agree with everything HRH His Freshness says.
I have never been in Geevor adit but understand its one of the best trips in Cornwall. I have tried in the past to get on a trip and been looking forward to a "permission granted" trip that didnt happen (as mentioned above).
We all know the "St Just lot" are allowed in but you deny others, to then get upset that your lock was chopped on one of the best trips in Cornwall seems a bit silly, you really should have anticipated this and maybe shrug it off or at least learn from it.
When you deny access like this, you isolate yourself from the wider community, its a great shame as you miss out on all whats going on, also posting in this manor is going to put all eyes on your site and maybe even publicise it to a wider audience.
Before you think I am a C--T, please realise I am a regular paying Geevor customer. I visit many times a year, eat in the restaurant and bring other people to see the site. We are all interested in the history of Cornwalls mining, some more so than others.
I am not your enemy, much to the contrary, you just need to take a step back and consider the wider picture. LET US HAVE A LOOK AROUND!
Exploring the mines of Cornwall and making some bloody good mates on the way!
