Florida posts a lot of saltwater information on their web site which is www.MyFWC.com.
They have a new item called the fishing pier finder which helps you locate not only piers but beaches, jettys, bridges, etc that are places to fish. You can get to it from the general web site already mentioned or go direct with
www.MyFWC.com/PierFinder. It is fairly complicated but has a lot of built features that can be helpful. I hope this proves useful to some of you.
