Accept judicial externship offer?

I'm a 1L at a T75 school and so far the only offer I have received for this summer is an externship at a state superior court. It would be unpaid, the commute would take over an hour, and I didn't feel a strong connection with the judge in the interview. I don't have any other offers yet and I have only one other interview scheduled, and I'm worried I won't have any job this summer if I don't accept. Advice?
