I fly fish for SM all summer in the Shenandoah. I would take some chartreuse poppers (sky blue is hot here, but I have had good luck with chartreuse also) and some crawfish patterns. Check out FOTW archives for examples. I fish the crawfish under an indicator, drift them through the deep runs, close to the bottom, sometimes 7 feet below the indicator. When the indicator twitches, set the hook with all you got, both with the rod and stripping hand.
