This is probably a rather odd question, but I live in an area that's fairly heavily mined (Flintshire) and on a quiet still night when you're sat out the back, I swear I can hear water dripping, as though it's falling quite some distance into a big pool.
I've heard that there is a big cave underneath this hill (Trial Hill), is it possible that I'm actually able to hear water falling inside the cave?
Or am I just going mad?
If I really am hearing water falling inside the cave, does that mean that the layer of rock between me and a great big hole in the ground is actually really thin? ... it's limestone around these parts, so could the cave roof be getting thinner and thinner ... is it safe?
