Hi all
there are a few things that can be said up-front:
- it must be in the nothern hemisphere, around the same northing as Paris/Moscow/Tel
Aviv
- it must be West of Europe and East of China
- therefore it's in the center of the world (the US) ;-) ... the only ones left using
miles ... ;-)
- measuring from i.e. Paris and Hong Kong you end up with Kansas and surroundings ...
- let's guess it's in the geographic center of the center of the world ...
- therefore it could be Lebanon, Kansas ...
... at least the distances match up pretty well ... (see
http://www.indo.com/distance/) ...
regards
Flavio
