To illustrate my response to Carpe Diem # 1020 rainbow, I did a quick search that found more fine images of rainbows than I could view in a lifetime. The image used here jumped out because it has a vertical format, does not need the rainbow to grab me, and hints at a futile yearning. The termite mound in the foreground looks like a hand trying to grasp the rainbow.
Termites are much too busy building mounds and digesting cellulose to indulge in such yearnings. Humans are busy too, and many of us have some awareness of the geometric reasons that a rainbow is forever out of reach. We sometimes yearn anyway.
No Pots of Gold
Seek ends of rainbows.
You will not find them? Okay.
The quest is enough.
The image used here is a photo by Randy Olson that was available at the time of posting as computer desktop wallpaper from National Geographic.

I won’t find a pot of gold? Well, there go my retirement plans.

I once had a friend tell me, in all seriousness, that he had actually “driven into a rainbow”. I asked him what he saw. He excitedly said “there was a beautiful golden light all around”. I asked him what he had been smoking. He got mad at me because I “didn’t believe him”. Your haiku was a kind of conversation and it reminded me of this incident, which occurred maybe 30 years ago.
I’m now seeing your punctuation in your haiku’s after Poet Rummagers comments. It is unique and complemental.
