Help with a life project

So. My top books are still city planning and architecture books. I want to know more, help DC grow without losing its character, and generally create a more sustainable future.

In other words, I want to get a degree in Urban Planning (possibly with an "and Public Policy" thrown in). I don't have the foggiest idea how to find funding for a graduate degree. I know that I can't afford it by myself in the near term.

Has anyone ever applied for grants for graduate work? How likely is it to get one for something that isn't a hard science? I'm soliciting advice.
