After a few days of thinking and searching for apartments, Amanda and I are about 99% sure that UNC is the place to go. Personally, my passion is with anthropological research and writing, which this degree will certainly allow me to do. I think the job market isn't such an issue either, I'm flexible in working in academia or working with NGOs and I also have pretty extensive connections in Europe which opens that working market to me.
The offer is almost impossible to turn down, UNC is one of the best-regarded public schools in the country and has the most interesting anthropology department in my opinion, plus the research there is quite similar to that of Wageningen in that the researchers are keen to provide useful information to social movements and economic movements in the Global South.
The decision was made pretty solid when I got a sign at work, someone had brought 'tar heel cookies' and left them in the kitchen, and nobody brought Peace Corps cookies. So it looks like I'll be teaching anthropology for the next couple years while taking my own courses before going back to Bolivia to finish my research there.
If anybody wants to see Boston, they'll have to come out before August! I'll be on a Amtrak sometime in early August and Amanda will come down probably a week or two later.
Thanks for all of the advice and support!
