Commuting from Alameda to San Francisco
Several have recommended Alameda on account of the ferry. I will second those in favor. I used to commute from Alameda to China Basin (essentially next to the CalTrain station/across from the ballpark but near Mission Bay). I took the ferry, brought my bike on, and then rode down Embarcadero (where you are allowed to ride on the sidewalks but need to navigate pedestrians, dog walkers, etc.). Oddly, my commute was the highlight of my day. There were frustrations - navigating crowds on game days, I missed the boat sometimes, riding in the rain, cheap bike spokes rusted and broke from saltwater exposure - but you really cannot beat that commute if you need to get across the Bay. I do also agree with those who suggest living in SF. It is hard on parents to waste time commuting - it is time away from family.
