Standby… digging for the street view screen cap I took at the time I dug all this… it had a concrete advertisement sign out by the road.
First pic is her driveway entrance and what you see from the road (which is nothing).
Second pic is street view cap that shows the concrete advertisement sign. I took the screenshot on 4/21/2018. It looks like the image used for street view was from 7/12/2015 (upper right).
That 4,800 sq. ft. "shed" was put up in 2015. Concrete company might have poured the foundation or slab for that.
Attached info was as of April 2020.
Improvements are on the second page.
