Most of my ride is through Golden Gate Park. I ride a couple of blocks to the Panhandle, into the park, and out almost to the beach. My work is just 2 blocks north of the park and 10 blocks from the beach. I'm lucky to have such a nice commute, but lots of people drive like idiots in the park. Door to door takes me about 25 minutes, much faster than the bus or driving and parking.
