Is that a pic of the real rainbow??
Holy Cow...so beautiful!
May he rest in peace.
I don't see anything in the photo to contradict this. The center of the circle of the rainbow arc s/b opposite the sun, and this accords with the landscape lighting. Beyond that we only require that there be raindrops in the field of view along the lines of sight to the rainbow.
One can investigate all this kind of thing with a garden hose mist spray on a summer afternoon.
May God rest Arnie's soul.
That looks like it was taken at the airport. The Fox video shows it from a different angle at the golf course behind what looks like a statue of Palmer’s father.
