The jellyfish would scare me off as well. Out of all the years we lived in Virginia Beach I only got stung once and that was enough for me. Ouch! Didn't even know what had happened. One moment I was bobbing in the waves laughing and chatting with my friends, next thing I know my upper arm felt like it was on fire! I am a pretty stong swimmer and the water wasn't too deep where I was snorkeling. Plus that is why you have to wear the inflatable vest, it keeps you floating on the surface. Not to mention there are tons of lifeguards around keeping a close eye on everybody. Scuba diving, don't think I could do that. You go way too deep and you are out in the middle of the ocean with nothing but your oxygen tank keeping you alive. Too scary for me! I'll stick to snorkeling.
