I've spent alot of time at bolth the Oakland and San Francisco camps.
that being said the oakland camp was harder to get to safely on foot, seeing as you have to cross into downtown at night regardless of where your coming from , but granted you have your wits about you it should be a piece of cake.
Oaklands occupation is in my opinion alot more organized than its sister tribe across the bay.
I encountered alot of kind gentle folks, who were happy to involve me in what was going on.
i spent two weeks at this camp, and ended up participating in the taking of oscar grant square, got my cheek split with a billy club and tear gassed for 30 minutes but managed not to get captured.
it was a beautiful thing seeing 2,000 plus people calling for mass assembly and peacefully carrying out the entire thing.
There were at least two times where all out battle broke loose in downtown. But the camp is still there and active,
but its location has been changed.
San Francisco on the other hand carried out multiple marches and even managed to close a few banks for the day.
although progress is slow the community here seems accepting of the movement. while some suits just two blocks away vary in outright opposition. Better food at this location too. The SFPD seem way less brutal than OPD and have yet to hurl mass ammounts of brute force and tear gas twoard the encampment which is located right at the end of market street after you pass the vendors downtown in the financial district a mere stones throw from the embarcadero and the waterfront.
