If I had to do it all again, I maybe would've gone for Geography. (but am still pretty happy with my international affairs BA)
Geography = a major that combines the human element (political/human geography) with a surprisingly technical and lab-focused element that almost ventures into STEM territory. Of course, as an IA major my geo courses were just bare-bones basics (ie, Geopolitics 101), but some of those 300 and 400-level courses....them fools had some pretty cool toys to play with.
And also, I met some folks later on overseas who worked for the NGA, and they all seemed pretty chill.
I applied for an internship with them last week! Hopefully it goes well that would be a dream.
