Coming to Cbus (a/k/a Scioto City

) Thursday. Since I left OH 8 years back, my recollection of OH law is foggy as to circumstances where my wife (no CHL) is in the car with me. I haven't had to think about her exposure, as down here, no CHL is required to have a pistol in your MV. It's considered part of your domicile. I know there have been a number of changes to OH law since 2012. I'm good as far as it goes for myself - it's what I have to watch out for with her that has me thinking.
* Under what circumstances can I exit the car and leave her in the car, with a pistol there (and where can it be or not be while I'm out) ?
* Can we drive with a second pistol in the door pocket on her side (mine is in the center console or in the driver's side door pocket) ?
Any tips appreciated.
And before you suggest it -- no, we're not going near downtown OR High St. Anywhere else, I'll be checking Google Maps frequently for traffic clogs ahead.
