march and rally to show their support for Occupy Oakland. On October 17, the three American hikers recently freed from an Iranian prison made their first West Coast speaking appearance at Occupy Oakland, drawing an audience of around 300 people. The camp grew to roughly 150 tents that were used for both camping and to provide services to protesters and visitors.
