Tony - just let me know when you’re in the area.
Also - the other post about not being able to go straight up is that some of these places are considered "cavern" dives. Paradise Springs is one example. You can see ambient light all the way up from the bottom (around 100’), but, it’s a sink that goes down at around a 45 degree angle - more than 200 feet in length - to the 100ft. mark. Blue Grotto is similar in that it is considered a cavern. Even there at the 100ft. mark, you can see daylight. There is an overhang, quite large, that goes down to around 50ft. There is a "horseshoe" shaped rock formation that goes down to the 100ft. mark and has a rope for you to follow. Both great places to dive, though.
