Here's Mary (funny how she ends up in so many of my pictures) at an overlook. What you don't see here is the bypass bridge. High up on the right, you can spot one of the concrete supports for the bridge.
And yes, isn't it funny that they had to mark "DANGER KEEP OFF WALL" on the wall here? I guess some people don't realize they might slip and that a fall from this height might not be good for them.
