Did it with the family. The youngest got half way up, the other 2 could not. Difficult for a 5.4. I would say that most other sites would give it a solid 5.5 grade. Outdoor beginners need to watch out for the sandbag factor.
A little bit more challenging than Ground Zero, but also a great route for learning/practicing sport leading. A nice, long, fun slab, with a couple vertical bits. Lots of choice for how to go up, and the rock is great, awesome friction wherever you put a foot.
