"Ship lap" is a type of wooden siding. I can understand how a remote view would perceive a ship. That side of the house is two stories high, and a complete field of white.
Someone had mentioned a chimney, and that was another cool thing: there HAD been a chimney just above the key (on the roof) but I tore it down and installed an attic turban on the roof.
Deer waft through here all the time, and about three weeks ago, a hunter shot one up on the hill. It left a trail of blood going out my driveway.
