Corkscrew swamp is amazing for the size of some ot the cypress trees - very ancient. The problem I had with boardwalk is I was trying to get a large view aka Clyde Butcher; but most of the boardwalk gives a very enclosed feeling (as I remember it). There are a couple of open areas where smaller cypress trees are growing. Wish I could make it this weekend; but its a bit of a drive from the far North (Florida) - about 8 hrs. Good luck with your abstracts.
