summers are everywhere in the mac, my buddy hooked into one today but it shook the hook after doing about 7 rolls in the water. and just becuase the mac and willy are mainly hatchery run steelhead, doesn't mean there arent natives in there! i can bet that there is native steelies in there that ppl don't hook into cuz the majority of the run is hatcherys and thats wut u will most likely get into... i am a stong beleiver in native steelies in the wily and mac. if they go up the "coast fork" willie, then y wouldnt they go in the main stream of the willy/mac? I will fish it until i hook one! They are there... there is steelies that do make wrong turns!
