Walk around the corner to the right of Mensus and The Big Chill. Fever is located between two other routes- Stormrider to the left(5.llb) and Delirium to the right(5.12a).
Fever starts with a crack that can be laybacked. I found the crux to be the starting moves until you reach a series of jugs near the second bolt. The top of Fever gives one a nice finger jam to the finish.
This is a fun and exciting route with good moves and position.
