Drugs! On my very first ocean dive, we were in the Bahamas (Nassau with Scuba Centre). Lots of sharks to look at, we had a few minutes to look at a newly submerged airplane, and of course all the fish and coral you could shake a stick at. Sensory overload for a newbee like me. Then we followed the group along a short ledge to a level area, still watching sharks and now I finally notice some of the fish and wishing I had taken up diving years ago, when I spy a large brick-sized bundle just below me. Looks like someting tightly wrapped in celeophane, just like one of those bicks of narcotics they cut open on TV when they bust into the smugglers boat! Ok, I'm newly certified and afraid to touch anything less the scuba police take away my c-card, so I get the DMs attention and my buddy and I point to it, proud as can be of our great find (reward perhaps?). The DM shakes his head and holds his left had in a fist in front of his face, while making a cranking motion with his right and panning left to right. Oh, that's right, he mentioned during the dive breifing that they were filming a movie from the next boat, which was going to move some of the sharks from the "pit" to our dive site...
