As a frequently traveler from so cal to the bay area, I'm looking forward to an alternative to flying. Right now what I'm actually watching is to see what happens to my local public transportation after high speed is built. For example, in so cal, a major hub will now be Anaheim. In the region around Anaheim, good public transportation is not readily available. What I'm hoping is as the trains links up, our local public transportation will get better to the hubs to travel up to the bay. I think something like this is important to try to get a system like BART in so cal.
