Thanks for the reply. The subtext is yes, I much prefer Boston and want to go. I can't keep my current job, but at Uniformed Services, you get paid through a government position, so very stable (not subject to grants, etc). Boston is a much higher ranked program, and would position me better for future academic positions, and USUHS is a DrPH as opposed to PhD (Boston). Also, because Boston is a larger school, there is much more opportunity to take classes in other disciplines, and I really like the professor I was assigned research.
No you're right, there is a possibility he won't get that one, but DC is more stable because he has a good job here now anyway, which is why the stipend wouldn't matter as much (since I don't need to support us on it for any period of time).
And so the cyclical discussion of pros and cons continues...April 15th approaches....
