I was visiting a friend who had access to a private island out of Charleston,S.C. As we were driving around the area, I saw a pond with a big raft in the middle of it. This was a common sight in the area I grew up in, and it was usually meant for swimming. I remarked that it looked like a nice raft for diving in to the swimming hole –after all, the water didn’t look that dirty. My friend looked quite surprised and told me that the raft was put there for the alligators to sun themselves…oops!
