You need to be aware of the northern and southern beaches of St. Johns County. Matanzas is a Federal land. No MD'ing. From the Mantanzas beach access ramp - north, is wide open. This is also where the concentration of visitors will be. The Vilano inlet/beach can also be detected. Going north, the GTM reserve is federal property. Don't worry, you won't miss out on anything there as no one goes there. Have fun and good luck. You will probably run into me as I hit the beaches often. I'll be the one with a Garrett Sea Hunter II.
