Scholarships for Grad School

I've accepted a spot in the University of Pennsylvania's Master of City Planning program. Now I just have to find a way to pay for it. I'm trying to reduce the number of loans I have to take out by looking for funding from outside sources. I've applied for one of the scholarships on the APA's website. Does anyone know of other organizations/companies that offer grants for planning students? Any advice you can provide would be appreciated!
