Feel like you are the first
It is a strange thing that even in cramped and crowded places like England when you go on the river you can feel as if it is just you and the elements of nature. On many stretches of river you can find yourself seemingly far away from the hustle and bustle of everyday life. If you are lucky you will be out of earshot and away from the stink of cars and roads. The only sounds coming from the ripple of water beneath you and perhaps the rustle of the wind in the trees along the bank. A splash here and the call of a crow there or the song of a bird nearby.
I always feel that the drone of an aeroplane above always adds to the warmth of a summers day. Perhaps it matches the drones of fat bees in the meadow.
The point is in the right circumstances it can seem if you are exploring a river and country for the first time. You can pretend, or dream, that no-one has slipped down this stream before.
The world is new and you have discovered it. The day is stretched out before you, unknown and slightly dangerous. You are ten years old again and in the country of your imagination.
