"Light at the End of the Tunnel"
When walking closer to the end of a tunnel the light gets much bigger and brighter. You must choose to take those steps forward or it may never get brighter.
The sun setting through the trees creates a moment of the brightest colors before falling below the horizon. It is a way to appreciate the small moments in time that get us where we need to be. It might take more than a day to get to the end of a tunnel.
