Jake: (opening narration) They say that the shortest path between two points is a straight line. But what happens if that path gets blocked? When sediment impedes the flow of a river, it redirects. Zigging and zagging instead of following a straight course. What looks to the crow like meandering is to the water, the most efficient route from source to outlet. Nature finds a detour. When two points are destined to touch, but a direct connection is impossible, the universe will always find another way.
