We don't know.
Last Saturday we headed down to St. John to see Cirque du Soleil. It was great. On the way down we're driving along (S and I, and sister and brother in law), and we see what looks like a rock in the middle of the highway. As we drive past, we realize it's a big turtle. Just hangin' out in the middle of the highway, waiting to be squashed. We turned around and Stephen jumps out of the car, grabs him and runs him off to the side of the highway to some water nearby. Poor little guy! A bus flew by a few seconds later. He just wouldn't have made it.
Wildlife conservationists we are!
