I wrote this song about a real experience. A friend and I, when we were teens, took a rubber raft to a swollen stream after a huge thunderstorm. We could float through this pretty well, but it joined a much bigger stream or small river, and we could not control the raft. We managed to bail out on a low, rural bridge, keeping just one paddle, while the raft and our other stuff was sucked under the bridge. We never saw it again.
But this song is also about humans in general, trying to control the natural world, and ultimately failing.
The song is available on all streaming services, and if you do not have a music service, you can access the song on YouTube: https://youtu.be/CsmmG_TBhQo
