Bike expedition

Took our bikes on an expedition today. Over the bay, across the Golden Gate Bridge, through Marin headland, over hills, along cycle paths and eneded up somewhere near San Rafael. We nearly made a full circle, but you can't cycle across the Richmond bridge. Luckily there are bike racks on buses here, so we took them back to San Francisco on a bus journey and then on the Bart back to Berkeley; achey limbs!
