The groups began assembling early today, especially VOCAL which drew crowds and photographers as it painted banners and put up its display of photos of Silvia Hernandez (la Chivis), Maria Guadalupe Sibaja (la China), and David Venegas (el Alebrije), the two companeras arrested Monday and the companero who has been in prison since April.  The FPR set up loud speakers and a sound system to make announcements during the day, with Florentino Lopez making the call to head over to the Zocalo at 4:30 fascist time, 3:30 popular time.
