City CarShare's new Polk Gulch pod in San Francisco is now open! You can now rent a brand-new Scion xA from the Polk/Bush Garage (at the corner of Polk and Bush Streets). To see a map of the pod location click here. The pod is located on the lower level of the garage; City CarShare members can use their fobs to enter the pedestrian door on Fern Street, see map for details.
