Here's a summary of the Berkeley campus event:
The castellers did a short parade march from Sather Gate to Sproul Plaza accompanied by pipes and drums,
went down to the lower plaza in front of the Zellerbach concert hall, and spent about an hour forming five or six
towers of different configurations - most were 6 levels high, but one was 10 !
The last setup featured 4 across of the littlest members, who pulled out two Catalan flags, a CA state flag, and a flag of the USA.
Everyone was in the usual laid-back and friendly mood that we associate with Catalunyans; they even invited us to help buttress the tallest tower. The details were interesting - no eyeglasses during the formations for safety reasons; the smaller climbers use the wide black sash that everyone has belted around their middles as toeholds to get up on to the shoulders, etc. The rhythm during the climb down was just as important as during the climb up to avoid any falls...
