I got my answer about swamps too. The Louisiana swamps are like the swamps in Northern Florida - lots of trees. There were gum, cedar, and cyprus. The swamps in Southern Florida are more open. It was a wonderful way to spend a beautiful Sunday morning. A couple of times the guide stopped the boat, cut the motor, and we just sat. We watched the animals, saw some snakes, and of course gators. The sounds were better than anything an iPod or any other stereo could deliver. Bird songs came from every direction.
