Way off for me, but no way before 12-14 honestly. That said, we live a far distance from any stores. It'd be a 15+ minute drive to the nearest big store. Maybe a pop down to the local gas station at 10-12, but I'm not sure how comfortable I'd be with that. It's a long time off and it depends on what kind of technology we have at that point. If I have a security system with cameras I can access from afar, I'd feel more comfortable than if I didn't. If kids had phones I'd feel different. I guess it will be a bridge we will cross when we get there.
Also though where we plan to move it would be next door to family, that would change the equation. If the neighbors were home and responsible and know I'd be popping out, that would change the equation as well.
