This is Bethesda, the area in/around that funny triangle of the DC beltway and the I270 split.
I am quite sure they have public utilities of every kind to the house.
And being close to DC, and actually being liberal haven Montgomery County where we must “welcome” everyone, it’s probably either a drug lord (illegals) or Moslem bomb plant (esp. with wiring).
The eastern part of Montgomery county is an alien world. How can 3rd worlders afford to live there when the average house costs 400K and taxes are $800.00/mo?
They make a federal case out of any building infraction here and it takes years for anything to get approved, especially gas and electrical. It took over a year and $12K to move my gas line a couple of feet.
Actually there are quite a few private fallout shelters in Bethesda and Potomac.
One WII navy vet had a sizeable lot for that area with the top of his concrete shelter rising about 2 feet above grade, which he had disguised by building a gazebo on top. Looked perfectly normal in that setting. He told me that at the time he built it there were several more in his immediate area. Sign of the times.
