Here's a scene I hadn't come across before.

It's looking down from the ramp from the subway to the Gotham Gate, and shows people that came to the Fair by bus waiting to get up onto the ramp. This slide was processed in May 1964. I wish I knew the exact date so I could avoid it when I get the time machine woking. Looks like it was going to be a busy day!

Holy Moses! 

'splain some more please?

1) This is the bus parking lot south of the subway, right?

2) They had to take narrow stairs up to the subway ramp?  That's the bottleneck?

3) There was no way for them to go to another gate?

4) Were there express busses from various points to the fair?

[Bill Cotter]

1) Yes

2) Yes

3) No - the train tracks were between them and the Fair

4) Yes, and this was also used by charter buses
