I did an FT search but it didn't bring up anything relevant, including your previous post. Thanks for the reply. If they are only available at a newsstand, I probably be out of luck due to the late hour of my arrival. However, if it is indeed an MTA machine, then I may be in luck. A search of the MTA website for the LGA area did not bring up any MetroCard merchants. I don't think there was a search for machine locations.
