I belong to another club called Subterrainea Brittanica
https://www.subbrit.org.uk/sites/milwr-tunnel/ Which is where I first learned about the Milwr tunnel. They don't do caving but organise the occasional field trip to ROC bunkers etc.
After some googling, I found Ian's video (no longer available) of UCET exploring the Milwr via the winch. A few minutes into the video, I recognised Steve Davies who I was in college with. I put "Join UCET" on my to do list but didn't do anything about it.
2012 was a proper shit year for me and I was in quite a dark place. Yearning for some sort of escapism, I started ticking things off my to do list..... And the rest is history
