Re: Book on Hatches.
Agree with previous poster but would like to mention that general books as I recommended are essential if you would like to learn basic entomology which you need to know to be a better fisherman. It is all fine and dandy if you can have a local hatch chart to guide you but the real problem starts if you can't tell a golden stone from a yellow caddis etc. A general understanding of basic entomology is fundamental in my opinion. This might not be an axiom for the mountains per se but definitely when you get in to tailwaters and lower elevation streams.
