Called today at a cafe connected to one of these show caverns, I call there just for a brew a few times a year just when I am passing, now a few years back the caverns flooded and water rushed out and across the carpark like a good size river, this is what it looks like now,
This is what it was like in the flood this is a pic of a large banner that as been there for a year or two and I often look at it but this time something stood out, look around the middle slightly to the right and you can make out a yellow blob that seems to be suspended above the hand rail.
This is a close up of that blob, it is a yellow hard hat, I did ask one of the guides why it seemed to be floating in mid air he thought it was hooked on to a fence but it did not look that way to me, he did have about 3 looks at it but did not seem to go for my explanation that the guy wearing it had run so fast he had left his hat in mid air.
It does look a bit strange and why after so long and many visits I suddenly noticed it I don't know.
