Bob would tell me of the time he and another caver, whose name I could not now recall would explore the cave to a river and beyond, and on one occasion the water in the river rose and meant they needed to spend the night there sleeping untill an exit was possible.....
It was a Cave he spoke fondly of......
In those days if someone found themselves caught down a cave due to flood waters they would just wait it out and exit after the floods receded.....
