Based on a fairly recent observation, my guesstimate, including a cord in the basement, I visualized what my 12 cord looks like, I'd say she has ~15cord.
15 chord a quarter mile long is 16" wide x 1' high, maybe you should adjust your stacking techniques so Backwoods Savage doesn't get confused.
I can't remember, but I made a pretty good guess this spring when I was in her yard. Maybe 17-20 cords in her Suburban back yard. There's A LOT!
