To the previous poster: Yes, Harold Washington Library is at 400 S. State St. I looked in the current city yellow pages, and while I did NOT find either a United Veteran's Cab nor a Veteran's Cab company...the 1/2 page ad for American United Cab Association says, in the corner, "Chicago's Only Veteran's Cab Association". So??????? Their phone number is 773-248-7600, but, sorry, there's no address provided either in the ad, nor in the white pages. Good luck. This one sounds like a real wild goose chase, but hopefully it will work out for you! I guess I've chased leads this obscure before, too! Bonnie
