Black Rhadley Cave - Shropshire Hill Walks

It says on the OS map that there's a cave on the side of Black Rhadley hill. But I know from experience that finding caves isn't easy, and it took two attempts to find it. When I did, I discovered that the entrance is fenced off, and there's warning signs. I was so curious.. I could see the hole, and shining a torch didn't reveal anything. How big is it? How deep is it? The only thing I could see was how dark it is. And walking on my own in remote places like this, I can't take risks. I knew not to get too close, and you shouldn't either!!!
I came back with camera gear that would allow me to look inside the without entering the fenced off area. But only when I got home did I see if the camera had captured anything... let alone the full truth behind Black Rhadley cave.
