A
shibboleth by which
out-of-towners betray themselves. No New Yorker calls the street
"Avenue of the Americas" even though
the street is clearly labelled that way; they call it
"Sixth Avenue" because it is a more
poetic and suggestive name.
Another test of out-of-townliness is "Houston Street" - the uninitiated pronounce it as if it were a
town in Texas. It is pronounced Howston like the
director.
