I love Baltimore. I've lived here for four years and I will be really sad if I leave! Even if I end up at Penn or GULC, I will probably either live there during the week and come home to Baltimore on weekends (penn) or commute every day (GULC).
If anyone has questions about life in Bmore, I'd be happy to weigh in. I can't say much about University of Maryland, although I did go on a tour and like it. I'll be visiting again on April 4 for the Leadership Scholars interview. I may end up at Maryland in the fall - it would certainly be the most convenient for me, since I live in Baltimore, my husband is in grad school here, and we own our house.
On the Penn admitted student site, they have little bios of the current Public Interest Scholars. It looked like most of them had a few years of experience working in public interest after college, but it was in a really wide variety of fields.
I am also curious to know when these scholarships are decided - I applied to both as well
