I've seen some darn big silvers below whitney bridge in the recent past, chromers, not even slowing down, headed straight up. The boots will bite, but the chromers rocket right on by! If its clear-ish and the sun is right I can see 'em go by in the dozens (on the right day, at the right place ad nauseum) A couple years ago I watched my buddy catch a 16-18 lb chromer silver. That big in the green? No way! Yes, he has the photo as evidence... If you are extraordinarily lucky you might drift your egg and corky right into the mouth of one, but otherwise, lockjaw.
