There is a lot of discussion going on about crop circles.
Many people think the crop formations are just a joke.
They think that hoaxers going around with stomper boards make all the crop circles. Then there is a group who is convinced that at least part of the circles are a phenomenon that cannot be explained. Not with the knowledge we have right now. And of course there are people who simply don't know what to think of the patterns. Bert Janssen read in the late 80's for the first time about crop circles and he definitively belonged to the first group.
