M & I have been talking about the Whispering Wall for years, but whenever we’ve been in Grand Central we’ve forgotten or been busy doing things like catching a train to Beacon. Yesterday, after an afternoon at the research library, we found ourselves in the food court at Grand Central. As walked toward the 6 train, we noticed two guys in corners in an archway, diagonally across from each other: oh! the whispering wall! As soon as they left, we took their places.
