Green street, nr Avebury, Wiltshire.  
Reported 9th June.

During my flight to document the "Wankel," I discovered a
thought-bubble type formation in a canola field on the East side
of Avebury. It is quite old, as the yellow flowers are all gone
from the crop. The design has a striking family resemblance to
the "Dragon Larvae" in 1997. Hmmm. In the same field there is
also a small, goofy-looking scribble, which had been reported
some time ago, but not previously photographed.
