If that is all they do, making patterns in fields and disappearing...
Then I ask again, what are we supposed to do?
I really am going to go back to my idea of aliens messing with the
talking monkeys with car keys for a laugh.
Human or alien, someone is playing a game with the only conceivable
purpose of getting a rise out of us. Not a game I want to participate in
if the perpetrators are too cowardly or reluctant to reveal themselves
and their purpose.
