I'd recommend you take a day and drive South East down 98 towards St. George Island. The state park there is beautiful. There is a section that my wife and I walked down where no vehicles are allowed. It's very secluded and quite deep sand, but along the shoreline I've never seen so many crabs or sand dollars.
It was actually the first time that I had ever seen a sand dollar on the beach and after a 1/2 hour of walking, I got bored with looking at them as there were hundreds. The birds are everywhere and plenty of secluded beach shots.
Carabella Beach is a small town that is really only a one stop light ghost town, but it has the smallest police station in the world. It's only a phone booth on the side of the road....
That whole panhandle area is very cool to explore. We kayaked the Blackwater River and didnt see another person the entire day!! BUt then again it was mid-March, so it wasnt really tourist season yet.
Good luck, and you should find plenty of stuff to fill up that Epson.
