[ WP ] You find the gold at the end of the rainbow . What is it ?

As you drive down the highway, the rainbow travels by your side. You watch it's feet skipping and dancing over hills and farms. 
 
 Look out ahead! A traffic jam! Brake! @ & ^! 
 
 Must be an accident up ahead... 
 
 You are stationary now, in a caravan of banked up cars. The rainbow waits up for you, feet planted in a potato field. 
 
 But is in the potato field? 
 
 The cars behind me see it planted left of the field, and the cars infront see it planted to the right.... 
 
 So where is it? Who is right? And can anyone catch up with one? 
 
 Since sunlight bounces off the back of raindrop at a fixed angle, and the raindrops are everywhere, you realize that in fact there exist in reality an infinite number of rainbows - but you can only ever see one at a time from any point where you stand. And if you start moving, you are actually seeing different rainbows in very quick succession so that it appears to be the one object... 
 
 A farmer is in the field beneath the rainbow, you notice. Pulling up potatoes. 
 
 He ca n't see it, you ca n't see it, but he stands in an ocean of colour.
