Another Eileen McGann tune (she's really into the canoe stuff) is Whitewater. It's all metaphor, of course, but what folk song isn't?
Sang this at a "Rivers" themed circle a few months ago.

Whitewater by Eileen McGann

Whitewater's calling, the river's sweet refrain
Sings a chorus to the forest as it's shaking off the rain
The night was passed in thunder but the dawn is breaking clear
Whitewater's calling, and I'm moving on from here

And I'm moving on my way, letting go the rope
Casting off all certainty and reaching for that brightly shining hope

Camped here forever, at least that how it seems
Waiting for a clearer sign, I'm wrestling with my dreams
I thought that they would bind me but now I think I see
Whitewater's calling, may it teach me to be free

And I'm moving on my way, letting go the rope
Casting off all certainty and reaching for that brightly shining hope

I know the current's swift here the water's running deep
I know there's many rocks ahead I've seen them in my sleep
I know that I could founder just around the bend
But I love the water's laughter so I'll see it to the end

And I'm moving on my way, letting go the rope
Casting off dull certainty and reaching for that brightly shining hope
