[blindlaw] stores for the blind in the D.C. Metro area?

[Mike Gilmore]

Hi everybody,
 
I know this is slightly off topic but I couldn't think of anywhere else to turn (google didn't help.) I was wondering where those of you who reside in D.C./northern Virginia purchase your canes. Is there a store for the blind that sells canes, braille paper, etc. for the blind close by?
 
Thanks.
 
Mike
