My experience
1. Can't find the pix yet. If I do, I'll try to either post it here or online somewhere.
2. My experience with the Caves: My brother's ex grew up in the area and always heard it was haunted - so of course we had to go. It was semi touristy when we got there, so I wasn't expecting much.
But once you enter the caves, it's a different experience. The walls are smoother, and in long sections there are human heads carved out of the limestone, which look exactly like faces in torment. At the bottom, it levels off, and you can see a few of the places where the Hellfire Club had their meetings, up to the end of the cave, where there is a moat that is caged off and where most the the hard core debaucery took place.
What seemed most scary is how quickly it got quiet when the tours would come through. Me & my brothers were wandering around with about 20 other people, looking at the bottom of the caves the public could explore, and slowly people were leaving. Eventually, my brothers and I were the only people in the bottom, and it was very quiet and very creepy, like a tomb. Maybe the limestone adsorbes sound better than most caves, but rather than having a life of its own (most caves being a living ecological system of sorts) the Wycomb cave seemed dead, and faintly ominous. Then the next group came down, and everything was normal again.
It's definately worth looking into if you are in the area.
