No slide (as of yesterday), with the limited traffic, Highline is in great shape.
Be warned - this is a rough road with blind corners, silty sand and loose rocks (on occasion), and steep drops off the side, that will end anyone that goes over them. While the road itself is not difficult, due to the aforementioned parameters - intermediate or better skill and extreme caution is recommended.
On every corner stay as tight as you can to the inside; had 3 near misses yesterday with the usual idiots driving way to fast ?
