Well, on an uncontrolled range like that it would be ideal if you could get your wife to the basic safety point where she won't accidentally shoot you. Beyond that, with people down range, no one handles guns. No one. Want to load mags, fine, stay back off the bench. Actions open, weapons safe.
The real consideration on an uncontrolled range is being downrange and apart from your guns and vehicle when trouble shows up. I will not be completely empty on a range like that ever, usually take a slung long gun with me to post targets.
