Belmont isn't ideal, certainly, because the subway doesn't go there. But they do pack in about 100,000 people for Stakes day every year, a good chunk of whom take the LIRR there and back, and the rest of whom drive, so it's silly to say it would be inaccessible for a 25,000 to 35,000 seat soccer game. I've been there for a couple of full-capacity stakes days, both on the train from the city and driving, and it took a while to get out but not any longer than it would take to get back to Brooklyn from the Meadowlands on the bus. And a soccer crowd would probably be a third of the size of a Belmont Stakes crowd. The idea that they wouldn't be able to attract fans because of the $13 fare doesn't seem very plausible, either, given that plenty of MLS fans in other parts of the country pay $15-$20 every game for parking. This reminds me of the old plan to build a MetroStars stadium at Aqueduct. If I remember right, the plan was that the stands would roll forward over the track on soccer days, and roll back to reveal the track on race days, with the soccer field in the racing infield.
