Done, would you be so kind as to explain the mathematics behind your statement that Roswell is one of the few places on earth where the longitude divided by the latitude is almost exactly the mathematical PI?
If Longitude/Latitude=3.14159, then this can be shown as Longitude=3.14159 x Latitude. If we plug into Latitude any number greater than zero and less or equal to 57.2958, we get an infinite number of longitude points which range from a number greater than zero, to numbers less or equal to 180 degrees.
If we take advantage of the various combinations of the N,S,E,W designation of coordinates, we can easily plot the points generated from the above equation on any earth map, whether it is viewed in a 2- dimensional, or spherical layout. Thus rather than there being few points which meet your criteria, there are an infinite number.
If I have misunderstood your statement, please clarify.
