US Route 1, running the length of California, is one of the great drives of the world. And the large landscapes that line much of the drive make for some superb pattern spotting. This shot of a slopping cow pasture, along the Sonoma County portion of Route 1, was taken in late afternoon. The sky, shadow and grass field made near-perfect diagonal lines across the horizon.

At the Monterey Aquarium in California. Their otter exhibit was the highlight of my visit there. But otters, while cute, don’t make for good pattern photos.
