I saw this on Monday at 11am when I was on playground duty, so went back the same time on Tuesday in my break to take some shots.
At 11 am the sun came through the gates in line with the picnic table. The shadow it created was almost symmetrical as the table was lined up by the gates. So the pointed top of the gate and the patterns on the fence come through with the shadow of the table.
I'm uploading just the mono today.
Large is worth seeing if you have time.
Thanks for looking
The yellow flower in my April montage was from a sprout plant.
Andreweverhale was very close with "4 petals - probably in the brassica family - oil-seed rape?"
