On a more serious note, this talk has reminded me of the days I used to do day sailing in Raritan bay and Sandy Hook bay. One of things that you could do from Sandy Hook bay was to take a range on the WTC towers to check your magnetic compass deviation if you were so inclined. The centers of the towers were almost aligned in a perfect north-south true direction from each other. That's all you had to do was get to where the north tower building (which had the TV broadcast tower on it) was directly behind the south tower building and you had a perfect landmark for due north true.

Navigators term what Sam describes as a "natural range" as opposed to a purpose-built set of range marks or lights purpose-built to guide ships in a channel. Noticing and making use of such naturally occurring situations has always been considered the hallmark of a skilled navigator.
