It seems that the Demonstration in Berlin has the most dramatic pictures - Regarding the postings here.
Local Newspapers reporting 200-300 participants. I wasn´t there but i think 250 to be plausible by watching the pictures. And don´t forget: About 40 Sceptics where also there (I´ve recognized some of them, not all weared a tinfoil-hat - and not all are members of the "piratenpartei" or the "left-wing-Spectrum" as sayed in the Link Mick translated ;-)
That sounds quite a lot of people, but you have to know, regarding the german conspirancy-Scene:
If some of our German "Chemtrail-Gurus" announcing a big event, there will come 150-200 people. Werner Altnickel (Our "German Carnicom") hold a lecture in Berlin 6 Months ago, and there where an audiance about 200 people. Dominik Storr, Speaker of the german chemtrail-citizen-movement "sauberer Himmel" (Clear Sky) hold a lectrure in a small village "in the boonies", and it was sayed he had 170 visitors.
That seems to be the "german chemtrails-traveling-circus", following every big event on the scene...
To compare them: These are pictures from the bigest 9/11-Demonstration in Germany.
This Demonstration (pictures taken on the tenth anniversary of 9/11), was announced months before (as the global chemtrail-march was) and heavenly advertised by the Truthers Websites. Media reports 400-500 participants
If you wonder, why there is a "11.9" on the banner and not "9/11". Germans use a different format to write a date. We don´t use Month/Day (MM/DD) like the most english-speaking does.We would call 9/11 the "eleventh day of Semptember": Results in "11.9."
