Two childhood friends and I are planning a guys week fly fishing, camping and hiking. We are are setting our sights on Montana and Wyoming. Yellowstone Nat'l Park seems like it may be the answer to our quest.

We're coming up from TX (Jun-Aug timeframe) and will have about a week.

Any input from locals/natives as to which rivers/streams not to miss while we are up there would be greatly appreciated.

FWIW, I've already been actively reading the GREAT RIVERS section on FAOL related to YNP but we'd probably wanna narrow that down from 19 rivers to a more manageable number Unfortunately, all 3 of us will have to report back to work and reality following the adventure.
