Here’s the very provocative and insightful Matthew Williams interviewing the Italian crop circle artist and author Francesco Grassi (http://www.francescograssi.com/) . If you really want to understand crop circles, drop your preconceptions about the mystery of crop circles and read Francesco’s book : https://www.amazon.com.au/d/CROP-CIRCLES-Signs-Intelligence-Encounters-ebook/B01NBN25CD/ref=sr_1_9?ie=UTF8&qid=1497314838&sr=8-9&keywords=Francesco+Grassi.
Francesco demonstrates very clearly and logically how modern crop circles have their roots with the famous Doug and Dave, who were inspired by the Tully saucer nest and how most of the tell tale signs of so called authenticity are flawed. He also demonstrates very clearly and precisely, how to make the most complex crop circles, in a way that befuddles even the so called experts !
From Francesco, “Crop circles are a giant circular stage on which many artists have been taking turns for decades at different times. Each one performs his number; some stay, others fade away. Some bring innovations, others recycle obsolete acts. There’s always room for everyone on this stage, and there’s always a new audience ready to applaud. Some stay, others fade, but the circular substructure is always there, firmly anchored with solid roots.”
If you’re interested in the people who are drawn to crop circles, you might also like to read Jim Schnabel’s Round in Circles (http://www.jimschnabel.com/ / https://www.amazon.com/Round-Circles-Poltergeists-Pranksters-Cropwatchers/dp/0879759348).
