I'm another Ohioan who is a bit concerned about it. My SO and most of his relatives are going to get the permits. I know them, so I don't feel uneasy about them carrying them, but when I think about the guy two years ago who followed me back to my place of employment, blocked my car in with his, and proceeded to scream at me about my driving, insisting I was soooo lucky he didn't just kill me, I get a little nervous.
My SO's argument is that now, I can get a permit and if that ever happens again, the guy might not be so keen to confront me knowing I might be "packing". I don't know that I buy that so much! He was beyond rational thought!
But I can't argue with the stats from the other states who already do this.
