Ironically I only live about a 7 hour drive from the so. Co. Rockies, and 1100 miles from the Smokies, yet my only fly fishing experience is the Smokies (own a couple of nearby cabins).

Has anyone here spent much time in Colorado on rivers and streams? If so, how does it compare to GSM fishing? Harder? Easier? Difference in average fish size?

My dad is primarily a CO stream/ river fly fisher and he claims the CO fishing is easier, more productive, and the fish are somewhat bigger. He also says the fish don't seem to hold in the same places at times. Of course, he cut his teeth in CO so that's his preference.
