Okay so i have my wreck diving cert....but i don't know how i feel about it *lol* it's REALLY creepy. I would much rather go cave diving. I sneakally did a run through in a cave in Australia (bwaha) because i saw it had an exit! THat's not true, i went in and THEN saw it had an exit, so i went all the way through...hehehe
It was long though. I was a bad girl. Totally freaked my hubby out...now to my credit i DID think he saw me go in...i mean hello, the water was like 200 viz and i'm the other big giant PERSON in the water, but for some reason he didn't see me, so when i came out and went around to get him he was flipping out *lol* poor guy.
Oh did i get an ear-full, and i couldn't even hear him!
Okay anyway, so i'm adventurous....but wrecks are scary!
As for jellies, i have seen the small ones, and have turned around to see like a hundred long tentacled ones, which i was veeeeeery careful to avoid on the way back to the boat...but thank goodness i haven't had one on me yet!!!
