Warm water fly fishing in the KC area should be easily accomplished. The area abounds in man made lakes and I can only expect there is some stream fishing available.

Trout, I have to agree with Betty about the parks. Too many people and "them ain't trout". When we returned from Wyoming 9 years ago I chose Rolla because it is in the heart of Missouri's Blue Ribbon trout streams. PM me if you have any questions.
