They are not paper cutouts held close to the lens because you can see THROUGH some of them. Click on that UFOwatchdog link. I read somewhere the father (banker) said it takes time for them to materialize. They are very wispy and over some period of time they become more solid looking. If you go to that first link, you'll see even more images where you can notice this more clearly. I have listened to Nancy Talbott (of the BLT Research Team - mostly crop circle research/investigations) talk about this and she is a very credible person. She is a researcher who just wants to understand how crop circles form and who or what is causing it.
And, again, as mercury said, there were OTHER witnesses.
this may be a new deal!
