"Windmill Hill of July 25, 2012 may represent a “lunar crescent” over a “trident”, to symbolize a conjunction of our Moon with planet Neptune on August 3-4, 2012" ( [link to www.cropcircleconnector.com]

"Why would those crop artists go to so much effort, to show us a relatively insignificant sky conjunction between our Moon and Neptune late on August 3, 2012? It makes no sense, unless the date itself happens to be significant in some way we cannot yet imagine. For whatever reason, this seems to be the fourth crop picture of 2012 to tell us a date of “August 4”.

First Manton Drove of June 2 showed us a “polar clock” which could be read as August 4 or 5. Next Santena of June 17 (in Italy) showed us the Sun and Mercury in Cancer on August 4, leading into another date of December 21, 2012 for end to the Mayan Long Count calendar. Then The Wrekin of July 21 showed us a triangular arrangement of Saturn, Spica and Mars on August 4. Finally Windmill Hill of July 25 seems to have shown us the Moon in conjunction with Neptune on August 3-4.

None of these astronomical groupings would be significant by themselves. In order to gain more information about this puzzling subject, we should see at least one more crop picture around July 29 (by the time series of July 21, 25, 29, ….) before August 4 is reached.

According to the Mayan Long Count calendar, July 26 would 12.19.19.10.10, while August 1 would be 12.19.19.10.16 and August 4 would be 12.19.19.10.19. A previous crop picture in July 2011 at Windmill Hill used Mayan numbers, as did Fabbrico in Italy in June 2012. Now at Windmill Hill in July of 2012, we have seen two separate series of circles as 10 or 16 matching August 1 in the Mayan calendar (or August 4 as 10 and 19, if three small circles have been “not shown”)."
