Regarding trap streets, as glancingly referenced towards the end of the Mountweazel episode, listener Glenn writes:
These are also known as "Paper Towns" and author John Green featured such a town: Aglo New York in his book Paper Towns. The story is that in the 1930s, Agloe, New York was placed on maps by (if I recall) the Esso Oil Company as a copyright trap. Then years later, they sued Rand McNally for having Agloe on their maps. But Rand McNally said ,"Look again, since you put that locale on the map at the intersection of two country roads, people have put up several buildings at that site and a sign that says Algo NY" So the copyright trap inspired people to actually create a real town.
That's a real fake place in fiction*, but in the factual realm of real fake places, has listener Jonathan found a paper school? He writes:
Talking of map traps, I believe I found one in Google, the gloriously named Upper Bottom School.
If I had a daughter, I would not send her there.
Can any of you confirm whether there really is an Upper Bottom School in Missouri? The links I can find to it all seem to be online maps, suggesting that if it is a copyright trap, it is doing its work.
*If you've an appetite for mountweazel-related fiction, listener Erin says: "The Borges story 'Tlön, Uqbar, Orbis Tertius' takes it to its imaginative extreme."
UPPER BOTTOM UPDATE:
Listeners, you make good detectives. I tweeted this out: Rotational Symmetry found a 1918 newspaper report about the finances of the Upper Bottom School district. Furthermore, Rotund Baker discovered the place's origins in Eugenia L. Harrison's M.A. thesis from the University of Missouri-Columbia, 1943: 'Place Names Of Four River Counties In Eastern Missouri.' About Upper Bottom School she writes:
In the northwest part of Boeuf Township. Originally there was but one school, known as Bottom School, established about 1868 to serve the entire Missouri River bottom along the northern edge of Boeuf Township. Later, because the territroy included was too large, the Bottom district was divided into two parts, Upper Bottom School to serve the upper northwest part, and Lower Bottom School for the lower or northeast part. (83RD REPORT; Supt's. Records; Miss Johnson: S.A. Hall)
Therefore, though satellite images of the location of Upper Bottom School show only the bare corner of a field, should we assume that Upper Bottom School was a real place at some point? Unless Eugenia L. Harrison herself is a mountweazel, in which case she was a mountweazel with a very substantial backstory regarding the history of Missouri place names.
