Gosh this is lovely Judith. You do have to reach for the camera quickly as it soon disappears. I didn't see a rainbow today so you were lucky and the sun must have come out for a short while to get this. I can't remember seeing the sun here. It really has been a miserable and cold day
Power poles are always a bother...part of the landscape but ugly and unnatural. Here by having them hold the rainbow you've put them to good use. Well done.
