Gee, thanks Gary! I put Thatch and Carvel on my list because they were the two recent places I have dived (what the heck IS the past tense of dive???) Not only do you need to do them mainly in the summer, you have to watch the tide changes, too. It was so quiet at the Tunnels that you could just sit and observe- usually you have to kick like heck to prevent crashing into the side...well at least I do... I love the bluebell tunicates there...reminds me of spring time in the hill country!<br><br>I have not seen a guide by Glanville and Jenik, but will be looking for it tomorrow, thanks!<br><br>And, Secret Harbour is on the east end of St Thomas- there is a phenomenon after the full moon (esp in the summer) that has to do with sand worms spawning that is incredible- thousands of glow worms all around!!
