I just applied for my permit last week, and should have it within 90 days. I have not yet made a purchase, and I am doing a lot of research on what I want to look at.
As it were, I'm in medical school, which is kind of a double whammy for "gun-free zones". I'm not ballsy enough or comfortable enough with my ability to conceal a gun for an entire day amidst 160 classmates and numerous faculty. Furthermore, the hospital is University property and is on campus, so once I begin my rotations, I still won't be able to carry. There is no parking on campus for students, so I couldn't even carry it with me until I got to campus and then stash it in the car, which I wouldn't have a problem with.
Also, if I remember correctly, in NC you aren't allowed to carry into health care facilities (it might be non-public facilities), which would mean that more than likely for the rest of my life in NC, I won't be able to carry at work. Still have to come to terms with that one.
