Fremont Canyon Guidebook

Is there a guide for this area besides Steve Petro's?

Yes, there is a newer one out.

The only place that I know to find it is this store in casper.

Let me also note that it is an improvement over the petro book in that it does contain some newer routes, but the descriptions of some of the older classics are still vague at best.

That guidebook is awesome. Especially the front cover picture. The only problem is that the model for the photo isn't given any credit.
