sounds

Not sure where to post this. I'm in the outer banks, sleeping on the beach, and there is a beautiful, high pitched ringing sound, like a finger going round a wine glass, coming from the ocean. It's pretty windy. Has anyone ever heard this or know what it is/ is causing it?

I think imma be heading from phoenix up to williston or somewhere close in ND to try and get me some of the fat stacks everyones makin cause of the big oil boom. This shit is ridiculous, my boy trucked his ass up there a month ago and hes makin 20 bucks an hour at tacobell lol. Anyone wanna road...
