What is your experience with Boston South Station?

I remember on your LIVE stream back in May exploring Boston and the Big Dig, which of course is awesome because it removes a lot of the noise and pollution from the surface and buries it underground, you got in to Boston through South Station. I am actually curious about how you thought of your trip by rail. I presume you got in by Amtrak Acela or Amtrak Northeast Regional? I am aware that politicians haven't really bothered with funding the federally owned railway and that sometimes Amtrak trains get stalled behind other commuter or freight trains. There is something so much better about driving or taking the train as opposed to flying, you see so much and it is rarely stressful unless if you get delayed by traffic or maintenance.

Also another question - have you ever been on certain Amtrak routes in California, like the Capitol Corridor or San Joaquins or Pacific Surfliner? I haven't but I want to know what the experience is like. Would you do Amtrak again?
