Hi John C, welcome to the asylum (sorry, website)!
Some of us are in this out of interest in mining, some from an interest in industrial history (my reason), some from local history, a desire to record what has been, before it all goes, some from caving, relatives - the reasons are so diverse it would probably take a week to list them all.
On the 28th, a few (11 I think) are off up to Moel Fferna for a bit of a look round. I've never been before, so really looking forward to it (that and SWMBO is glad to get me from under her feet for the day).
Madness takes its toll, please carry exact change
