DShock,

I am currently reading Bob Clouser's Fly Fishing for Smallmouth and he describes various color and marking configurations as it can relate to bottom color, water quality, and other environmental conditions. It is amazing to look at the photos from different regions of the country and note the differences. I'm only just starting the third chapter and can say that this is an excellent read. I have no affiliation with Bob or his book publisher, just a flyfish'in Ho!
