re: st augustine

Go take the boat over to Fort Matanzas.
Fort in town is great. Castillo San Marcos
The beaches North and South of town are fairly different and interesting.
The Ximinez Fatio House
National Cemetery in the same area downtown.
Oldest Schoolhouse
St George St has a few interesting things but is fairly touristy. Worth a walk down a couple of times.
Protestant Cemetery and the City Gates are at the end of St. George st.
The Lighthouse is fun and there is a nice new museum complex on site.
The Colombia Restaurant.
