Thats the rain coming

Yesterday I posted an image taken from the bridge at Pontoon. There were three of us sharing stories of fishing and poaching and admiring the view, when the sky turned very dark. We could all feel the rain coming but kept up the chat until the first drops landed still chatting , one of them declared "Thats the rain coming" when suddenly the heavens opened . "Good luck lads" said one and we all ran to the shelter of our respective cars, but as I sat into mine I looked in the rear view mirror and saw this rainbow, there was nothing for it only to go back out in the rain, as the the other two drove off , they probably thought me a little mad!
