The parade starts off mildly simply with people in costumes.	Then come the juggling unicyclers.	The mayor, in a city of Berkeley truck.	Likely, some fairly normal people that just wanted to walk in the parade.
An old marching band.	Yet more of the marching band. They're clearly not quite as weird as the Stanford Band!	Yet more of the band.	No, I don't know what he is or how he is traveling.
Sarcasm, or an actual protest? In Berkeley, one is never sure...	The "long ears good" truck. Is this a conscious reference to Animal Farm?	Excellent! The best "float" in the parade: cupcake bumper cars!	Excellent! The best "float" in the parade: cupcake bumper cars!
The first of many solar powered vehicles.	The first flying carpet.	Taiko! They stopped every few hundred feet to perform. Must be exhausting!	Lesbian boxing, guarded by bishops?
A closer view of the exhibit commenting on homosexuality and religion.	Jazz performers in training.	"Lord Fushmurai and Retinue" (See the Contra Costa Times article for more details on Lord Fishmurai.)	More of Lord Fishmurai's retinue.
Tibetans	Tibetans strolling.	Someone dressed as a "do not enter; emergency vehicles excepted" cement pillar, and someone dressed as an emergency vehicle driving all around the pillar.	A really big flying carpet with a bellydancer.
Proof of the largeness of the flying carpet.	Old-fashioned stagecoach, complete with horses.	Passengers in the stagecoach.	Strange woman with dog.
Anti-bush rally promotion truck.	Another person dressed as one of those cement pillars in the road.	More people making a statement about oil. (They were begging the crowd for gas.)	The same people also make a statement about traffic.
Is it a comment on the parade itself, traffic ordinances in Berkeley, traffic itself, or something else?	Peak oil people, followed by the polyamorists.	More polyamory people, along with someone with a petition. (There is a better photo of the petition near the end of these pictures.)	People advocating boycotting Berkeley Honda. (In short, it's because the ownership recently changed and the new owners fired a lot of long-time (20+ year) employees.)
Some people for democracy.	Anti-Arnold demonstrators.	Don't get me started on these people trying to stop RFID from being installed in the public library! Oops, too late. They believe (1) Spending money on RFID endangers funding for other library services. (Sure, but the library wouldn't spend money on RFID unless it saved money in the end, through having to hire fewer people or having less book theft.) (2) Privacy worries. (3) Unknown health effects of RFID. (What health effects? There aren't any meaningful ones.) (4) "Democracy abridged." i.e., having the library spend money "without adequate advance publicity or public discussion"	Promoting the Berkeley creeks.
