unfortunately, living in manchester, if i want to go underground i have a choice of wales for mines or yorkshire for caves.
all we have locally is facit stone mine, which is one loud noise from a huge complete clapse or a couple of old small coal mines, which do my knees no good at all.
i think north wales must host about 75% of the mine exploring community most weekends, we didn't actually have any plans at all yesterday, we met at my house at 7.30am and didn't have a clue where we were going to go, we just headed to wales, we were tempted to nip uo to aberllyn, but as andy had only been once a long time ago, he wasn't sure he could find the way in, so we just opted for the easy option, plus buddah had never been, so it was new to him.
