Rainbow at Breakfast

I stood up in the kitchen with my marmalade on toast in my hand and looked out of the window. What did I see, the most beautiful rainbow i have seen in years. Darted into the living room for my camera thinking it will be gone by the time I'm sorted (usually the case). I was lucky and took about 10. I now know where the rainbow ends. Just in front of my house on the mouth of the Clyde. Do you think I should go diving to perhaps find the pot of Gold?
