Unnatural Encounter

Yesterday they sprayed herbicide on the field across the street. It was actually kind of beautiful the way it sprayed out. It was misty and ethereal. There were all these white balls in the field and I couldn't figure out what they were, but then I watched closely for awhile and learned they they were ball of foam. If you look closely you can see one about to fall off the end of the right hand arm of the sprayer.
