Re: RMNP first timer
You got all the information you need in that book. Don't kill any Greenbacks or you will be in some trouble and bring all three rods or at least the 4 and the 6. Since you are going to be there close to runoff, you may want to fish some more of the still water lakes, which will hold the bigger fish.
Casting a 4 wt at those elevation in that wind is a pain in the butt.
