Hello fellow Hoosier, I also live in NW indiana. In crown point they had me pay $1 for postage, and the papers that I had to sign were the application, the fingerprint card, and one other paper (I cant remember what it said but it was just a general paper with my name, DOB, and which kind of permit I was filing for). Im sure it didnt matter what it was you were signing if the captain brought it too you, it might have been the last paper I just mentioned.
It is odd my town makes me pay for the postage, because i just took my fiance to get her permit today at the county building and they did not make her pay for postage. O well, as long as i get my permit before my current one expires. gl
