How far would you travel for an interiew?

How far would you travel for an interiew and what things would you consider in making that decision? i live in Clinton Township, Mi and have an interview in Grand Rapids(3 hours away) thursday. I haven't gotten any callbacks from jobs untill now and I graduate this month with my BA in management. its a management trainee position that supposedly pays well, but I don't know how much exactly. Should I go or wait for something closer to come along?
