Friday is the last day of the public exhibition of all five developer proposals, in a storefront near Grand Central. The exhibition includes design boards, models, and last time we checked, a representative from each developer on hand to answer questions. Those details again:
Rail Yards Proposals Exhibition
335 Madison Avenue
(Northwest corner of Vanderbilt Avenue and 43rd Street)
Across from Grand Central Terminal
Daily, 8:00 AM— 8:00 PM Until December 14
The exhibition frequently runs out of comment cards, so if you're heading there, make sure you bring your own paper.
The MTA has been a bit ambiguous on when the public input period officially ends (the exhibition was extended by two weeks due to demand). If you can't make it to the exhibition tomorrow, you can still view the proposals and comment online.
