Yes diving under and around the Blue Heron Bridge where Phil Forster Park is located is really cool at the right conditions. That is also where we have heards of flying gunards, fifty and more, during the right moon phases and that is also the place I've repeatedly found the striated frogfish, male and female and juveniles, but they move around a lot and you have to know where to look......... 
It will be good when the park construction is done in a month or so and it won't have to entered clandestinely "over the fence" or enter where the boats launch with lots of swims against the tidal current changes. I'm glad though that the place has had a quiet time to recover, let's hope another storm doesn't impact it this year for sure!!! 
Also Alex I must absolutely differ with you that the diving is "average". I've dove a lot of places in the world and I still find Florida diving amongst the best in the world, far above the average of the world and especially this part of the world. For one thing our reefs aren't so fished out like most all of the Caribbean, and I've seen as many as 20 sea turtles on one dive this time of year, green, loggerhead and hawksbill, probably just north of where you dove yesterday. Also I told James to get someone to take you to Hole in the Wall, one of the top dive sites on the planet as far as I'm concerned, but deep of course and you must have a good captain for a good drop or you will miss it as the reef doesn't even start till 120'. Still an amazing dive with prolific marine life and gorgeous viz as documented by Walt Stearns in your "One Best Shot 05" thread, I was right behind him when he took that photo. And rare small fish down there too. Just FYI, can't judge Florida diving or diving anywhere with just a few dives......
And of course Florida also gets whale shark, salifish, mahi, mola & all sorts of sharks, etc if you are lucky and diving in the right place at the right time!!! 
Glad you had a good time and you like America!!!!!!!! We aim to please you Brits of course!!!! B)
Thanks for all the shots of the seahorses and the shortnose batfish! Glad to see the usual suspects are still congregating there! I'm off to find even more unusual members of our Florida fish community in a few days with our "cryptic" species surveys for the Biscayne Park Service, I'll let you all know what more we find!! Have fun with your Bahamas sharks with all the chum............
