On our short dog walk we come around a corner with chestnuts:

The rainbow was produced this way:

The images where taken during a longish dry spell, where the farmers in the area started with irrigation.
Even without the rainbow, I found the water from the sprinkler interesting:

Actually, the first two images are nice, but more documentary, I like the last one much better, probably the tone of the light and the way the corn plants are lit.
