Of course, you then have to live near BART (or drive to BART) and then contend with the ZOMG GERMS!!1Eleven!
NYC was way...way better in this respect.
What prevents Caltrain to do better in terms of keeping up with schedule? Also, there must be a way to keep fare reasonably cheaper than cost of driving a car to work.
Me, I live near SOMA so I can stumble home when essentially everything but taxis is shut down.
