Cool, another Aaron! I'll probably run into you and monotreme; my advisor's main affiliation is the Nicholas School.
I will be bringing a car, but I plan on using it as little as possible. I'm hoping to find a place relatively close to campus for biking (I'm recently coming from Fort Collins, CO, which is a great bike town).
I am really excited about Durham! Did any of you visit cool restaurants, etc., during visits? The 9th Street area seemed pretty happening (one of my friends who lives in the area took me to Sam's Quik Stop when I was there; best specialty beer selection I have seen), but there are probably lots of gems that are not on that street.
