California High Speed Rail
It will probably cost a fortune and everyone will complain, but like most public works projects, when completed it will be appreciated many years after it is built and operational.
If you want to take train from Simi Valley to San Francisco. First you have to go downtown to Union station and then take a bus to Bakersfield to catch the train. It takes all day. I say bring on the bullet train!
