MIA and FLL
(more so MIA
though) are known to be some of the last remaining photography friendly airports. Because we are not in a increased (well I guess the level is always increased, but not to the point it was a few weeks ago-- I don't know the whole color code) the normal MIA
police officers are there (I cannot really speak for FLL
). They know the whole deal and support the photography, as long as you shoot in designated or known areas (the aforementioned holes and the El Dorado area on 9R
, see Art's site). Hopefully you come when there is high pressure because then the 9s, 8 and 12 are used which offer the best opportunities. When landings are from the east (when low pressure systems move through), you sort of need to search for spots on the oppositte side but it can be done with a little time. So just stick to open spots and the designated areas and you will be fine.
What else to do? Well it depends on your interests, being a teenager, we love going to South Beach where they have awesome bars and beaches and that is where the nightlife really is. They are also known for their food. Check out places like Espanola Way, South Point, Lincoln Rd., etc (all on the beach). During the day you can check out Metrozoo and the Seaquarium or go to the beach. Miami is really touristy so you have plenty of options.
The only good aviation stores I know of it Atlantic Models (try them on mapquest). They sell awesome models, obviously, and some apparel too. There used to be a store next to the airport which was amazing but unfortunatley they weren't generating enough business and were forced to shut down.
