Dove Manatee Springs & Catfish Hotel (2 springs within the same state park) during OWD cert dives. Manatee Springs has very high flow at the mouth of the cave(rn), but still very diveable across the odd underwater 'forest' landscape. High flow allows 'log wrangling,' which is walking across a fallen log across the entire opening, hanging on as if dangling from an airplane. Catfish hotel has more life (as name would indicate), and is deeper, but not as wide. Don't be intimidated by the duckweed on the surface: it's only a plant floating on the surface. Move it easily out of your way on entry. Bubbles clear it out of your way while you're under the water. Didn't cling to my gear, but there is a shower immediately upon exiting.
