But there were indications that the pranksters or artists were of earthly origin.

The MontereyHerald.com reported that guards from a South Bay security company were at the field Monday morning on behalf of a client whose identity they could not reveal.

Meantime, a YouTube video titled “Salinas Crop Circle Discovery” posted by user “Cannot Say” showed two men driving down the road at sunrise on Monday and then spotting a blinking green light in the field.

“Dude, this is a crop circle,” said one of the men after they ran toward the light and allegedly discovered the flattened grass.
