Geez, I hope I am not dominating this Crop Circles section too much. I have been critical of others doing that in some forums.
Nobody else seems to be posting here though, so I guess its okay.
Crop Circles are my special interest now - the "season" is about to begin, and it will be the best ever.
Link here to one of the early crop circles. I bet the early ones were not appreciated much, as they could not be seen from the air, up high, like we can now with planes.
