I grew up in southern California. I went to college in central California. I spent the following five years in northern California.
This means I lived in NorCal and had friends and family in SoCal. So several times each year, I would make the awful trek down the I-5. That drive is boring, it's expensive, it takes a long time, and it doesn't do the environment any favors. I knew MANY people in the same boat as me-having to make that drive at least three times a year (and back!).
So high speed rail between northern and southern California sounds like just about the best thing in the world to me.
To keep up with the ins and outs of the November, 2008 ballot measure, check out the California High Speed Rail Blog.
And here's hoping you get that done before I move back there...
PS: I've taken the Acela from New York City to DC and it's awesome-seriously.
