You say some reference route numbers don't appear on signs. I can
think of two possibilities to explain this:

1) The state maintained road doesn't have a small green reference
marker. Maybe it's too short, or maybe any markers that would be
present are frequently stolen.

2) The small green reference markers are not considered signs, and the
web page http://commons.wikimedia.org/wiki/File:NY_51_old_and_new_ref_mkrs.jpg
should have "[[Category:Road signs in New York]]" in the wiki source

Are either of these correct?
