I guess nobody has been there on the 4th. I was thinking that with the light restrictions, there would be fireworks restrictions. Perhaps a 4th of July party?
I've been there on the 4th but actually went out for the evening. I doubt that they have them for the reasons you mention. I did however see an excellent fireworks display at the Vero Beach Dodger game which is just a short ride away and a fun summer outing. I'd check their schedule and see if they are having fireworks.
