Re: Cell phone coverage. If the cell service were unreliable, wouldn’t they have a landline? Most older people resist relying solely on cell phones, anyway. We have a home in an area where coverage can be a bit tricky and still prone to storm damage outages (although it’s getting better because it’s a HCOL area and the rich people demand it), and we aren’t even that old, and we are not in a remote or isolated area, even. It’s just practical.
My point is, I wonder if he would have had to leave the house to make a phone call.
