Villas - There is a digital sign reading 'turtle crossing' as you enter North Wildwood Blvd. I don't think they can climb over the concrete barrier that separates the highway. So I looked it up and this is what I found: "While most turtles are not good climbers, a few species do exhibit some climbing ability. If you make sure the wall is smooth and twice as tall as your turtles are, they are unlikely to climb out." So there may be a back up of turtles on the wall.
