So there's a "National Federation of the Blind", or NFB.

The NFB is not NABM,and it's hard to believe that Mr Austin didn't know what organization he's the 'National Executive Secretary' of.

For all the web presence they have, NABM could be two guys (or one guy plus sock puppet) in a bar in Muncie Indiana. I've looked for evidence that I'm wrong, but so far have found none.
