I didn't read all of the posts here but many people are referring to local mass transit issues. Obama's plan is a regional mass transit solution. For people that need to get to major cities within a region. I think it's a good idea however I'm worried about the actual viability of the solution.
I could see California and the New York/DC Corridor having one but some of the others I'm not so sure of. This is also coming from a person living in the south.
