I was on my home from an outing the other day when I thought I saw what look like a fine jet of water squirting about 20 feet in the air. It was just as the sun was setting and I thought I was loosing it. There were hundreds of these jets in each paddock for around the fifteen kilometre tripI was on.
I asked my better half, and she said that I needed my eyes checked. Then she started to notice them.
Look at the brown spirals.
On inspection it was flying ants flying in a spiral. Each spiral about 20 feet apart... Weird.
