I didn't know your location. We used to be able to watch them in Ft. Lauderdale, but no longer. I found there are about 5 really good sites around the state and I plan to stop by one in Ft. Myers in a few weeks.
This is actually the same place I stopped by! One day I'll go up to the springs so I can see them more clearly. I was told that the males will flip on their backs in the courting process.
