After a fifteen year break, i ventured back into saltwater fishing along the Calcasieu River and in Big Lake, and some things have changes. I posted in another forum about a night fishing trip near PPG and discovered that I was fishing in a USCG Security Zone. I started asking around and a lot of people knew of the security zone but did not know the specifics. So I contacted an inside source and he provided me with the descriptions and images below detailing the security zones. I am posting this so that others won't make the same mistake I did.
