I ALSO had 2 somethings in my past that happened one 20 and one 30 years ago, but I could not remember the exact charges. I got a copy of my record from the state police, it contained one of the convictions but the other one, which i got from a DNR officer when hunting. I was also called before the board, which I knew was going to happen. I put down both incidents on my app, and the Monroe County board was not very concerned about them, although the Deputy for Monroe County did ask me to explain. But all in all they were not very concerned with something that happened 30 years ago.
I would spend the 20 bucks to get your State Record on convictions, while it may not contain all your convictions, you will have some idea of what they are going to ask you about. this non conviction will not be on the records, if it is, you were convicted. I know one person who though he was not convicted and later found out it WAS on his record. for 20 bucks in my opinion its a good informational tool to have. Others disagree, but for me it gave me a hand up on information when I went in front of the board
just my opinion
