The FTAA (trade talks) notwithstanding (the cops were told to be absolute assholes and people were warned not to get anywhere near the city during the trade meetings unless they wanted to be subjected to random searches and questions, my experience has been that Miami cops are some of the coolest around. (Ive spent most of my life in Miami but have lived in New York and Boston).
I have found that Miami P.D dont give a shit about drug crimes or anything else for that matter that isnt 'real' crime IF U RESPECT THEM and dont act like a total punk to them. Even if they find shit, theyll often just confiscate it (or use it). which is why I suspect that Phish booked the shows in the AA arena (where the heat play and which is in the city) as opposed to the Office Depot Center (where the panthers play) and which is in suburban sunrise and has much better accoustics for concerts but much more asshole cops.
(unfortunately, the AA just isnt as good for concerts as it could be because the bldg was built to echo sound so that it sounds louder at heat games than it actually is) Most of the time, if i go to a show, and have a choice, I go to the Office Depot center (even tho I live in Miami), if possible (many concerts/events will book at both). A cpl years ago, I went to U2 (the girl I was dating was a diehard fan) at both bldgs and could not believe the sound difference. Still, I can Not Phucking wait and Im sure the sound will be fine.
The shows should be a blast. havent been to one since big cypress.
