Chris,
I collected for many years south of a marina on Flatbush Ave, just south of the Belt Pkwy, we used to call that area "Dead Horse Bay". I don't recall the marina name, but its the only one there.
You have to go at low tide, don't bother at high tide. Lots of great tropicals there. Still too cold for the tropicals, but other local stuff will be there now. Some extra lead weights will also help in that area.
Just watch your net dimensions, etc. There are permits involved with certain larger size nets (both length and depth of net), but I don't recall the cut offs for "no permit" nets
