If you're traveling with a New York permit (just a wag based on "TheNYResistance"), I guarantee you it is no good in any other state. New York has no reciprocity with any other state.
Indiana and a couple other states recognize all other states alid permits.
As to the ops question, its a Florida issued permit so yes, unless miami has its own weird laws like nyc. Best to check ahead of time with the issuing authority of the permit in question.
