I'll second going. Of course, I came to a local fair in DC. No need to go to the technical parts even if in the military.

I found reading "Checklist for Success" was enough to get your mind in the game for the interview.

I talked to Delta, Continental, Northwest and a couple of smaller players that day after already having an offer with United. Got calls from all three within the next two month and one within a week. I'm betting the job fair had a big play in that.
