The last bolt on this route is bent and unclippable, and should be replaced
Highway to Hell follows long pulls between slopey dishes and thin edges up a slightly overhanging panel of marginal rock. The climbing is a bit off-balance as the line leans left, and the rock deriorates quite a bit near the top. There are many better 5.12a's around, and this is likely the worst 12a in the Aggro Gully, but if you are desperate for morning shade, this doesn't see the sun until 2pm or so.
On the east side of the Aggro Gully, following the first line of bolts encountered when entering the gully, then heading left when the bolt-lines diverge (Ghost Rider heads right).
~5 bolts to 2 Bolt Anchor.
The last bolt is bent and un-clipable resulting in a long runout to the anchor. Its an unwelded eye-bolt, so it could be girth hitched with a sling or wired nut, but even then who knows if it would hold a fall.
