I had a memory flash. The rain hitting the car sounded exactly the same. I was very young, back east, waiting in the car as it rained.
It made no difference, the rain hitting a American built car in the 50’s or 60”s or the rain hitting the Japanese car built in 2008.
I got out and saw the rainbow. The same as many rainbows, 50’s, 60’s or 2008.
