Faint rumblings in the distance are par for the course when on a river journey. As long as they are faint there is no need for anxiety. The rumbling could merely be a sign that the current is picking up a bit. Become and stay alert but don’t panic. They do not necessarily mean that more Rapids are approaching. They should be taken for what they are, just signs but not proof. Maybe the water is flowing a bit faster up ahead. Maybe a tributary in feeding in. Maybe there are rocks in the river. Maybe, maybe, maybe ……..
It is good to detect them, to be aware of them. It helps to be prepared for any eventuality and the course of a river is sure to be ever changing. That is the nature of a river and indeed the nature of life.
