LOL... yep.. there is no 4th avenue. The avenues in midtown go like this



There is a 4th Avenue down on the Lower East Side, however--at about 13th
Street.
Photo-Tech Camera repair is at that intersection . . . best camera repair shop
in NY.

Starts below 14th street. Also don't forget Avenue A, B, and C. (York is ave A below
14th as well).

Then when you get up to Central park you have Central Park West, Columbus and Amerstam
Avenues etc... There are another two dozen or so miscellaneous N/S avenues thrown in at
various places.
