Slough creek was crazy good when I fished it 30 yrs ago (summer after high-school) If you missed a strike you could just let your fly drift a few feet further downstream and another 18++ inch cutthroat would take a swipe. Not like some of the super selective cutts in the main yellowstone at the pull outs in the park. Wow, brings back some awesome memories. Rock creek in MT, the green for sure in UT, Popo Agie-Wind-Sweetwater in WY (large browns on hoppers and streamers)

Have fun!!
