MTA is not the name of NY City’s subway.
It stands for Metropolitan Transportation Authority.
They oversee all transportation in NY City –
Subway system, buses comapnies…they regulate fares and oversee bridges and tunnels, etc.
The fact that Peter Pan was mentioned in the MTA pic you posted (in your other theory about this),
makes me think the clue is more slated towards the Peter Pan Bus Co. rather than the subway.
The PP Bus clue goes hand in hand with the ‘Further’ bus that the real Neal drove from San Fransisco to NY City and is referred to in the Grateful Dead song as the bus to Never Never Land.
