Rainbow Trout and Floating

I have been asked in the last few days what it means when I speak about floating.
I live on a stream. One that is wide and deep enough in spots. for boating, fishing, swimming, and yes floating.
We have a small dock that jets out into the stream enough that I can take an inexpensive blow up raft to the end and jump right in.
Spending time just drifting on top of the water, bobbing and weaving, floating the minutes away.
Although I do not have rainbow trout in the stream that I am aware of, I have been inspired to paint them.
I love to float.
