Language & WorldFact
A town was invented to catch map copiers. Then it became real.
In the 1920s Otto G. Lindberg and Ernest Alpers of General Drafting put an anagram of their initials at a Catskills dirt-road crossing: Agloe. If it showed up on a rival's map, copying was proven. But in 1930 the Agloe Lodge opened there, later a general store. When Rand McNally printed the place, it could cite real county records.
Useful: Map makers still plant small errors to prove copying; "trap streets" are not a myth.
