spiderman ride manhole cover question

[taxman]

what does the manhole cover say at the end of the spiderman ride? just before you are webbed at the end of the fall the manhole cover comes up real fast. i tried to read the words on the manhole cover but couldn't.

 

[Figment22]

It says:

"Not An Exit"

Also, look for a special phone number (not on the manhole).
