Perhaps it was one of those secret map creator codes that are put in to see if people steal their copyrighted map
designs. I read that each map designer has their own little special red herring like “Turtle Street” which they put in to every city. Perhaps
Mapquest uses Felix.In fact, I searched Felix in San Francisco on Mapquest and discovered a Felix Avenue, which is in a suspiciously similar obscure location as the Houston Felix Street. Both are short little streets, located off of another obscure little street and end abruptly under a highway. Is it the same for your hometown? Try http://maps.yahoo.com/.
