For mountain bike riding in Arizona, this is the guide. It is fun to read. After checking it out from the Flagstaff library I bought a copy.

There is no Table of Contents; No Index; Yet it is reasonably easy to navigate since trails are listed alphabetically by region.

REGIONS
Flagstaff
Phoenix
Sedona
Tucson
(Other)

Sedona and Flagstaff get the most coverage. There are an overview maps of them in the front. Phoenix also has a lot of coverage.

Each trail has a map sketch on the left and a one page description on the right. ( )

Eclectic writing style of Cosmic Ray makes for an entertaining guide book. There really isn't anything else like it out there for Guide books - will shed some light on unknown places in Arizona to hit some singletrack. ( )
