Salt River yesterday 4/21

Put my buddy's jon boat in yesterday around non. targeting smallmouth we fished every piece of wood cover, current break and anything else that looked like it should hold a smallie and blanked. My buddy had one on a Texas rigged worm that got off and that was the only bite we had. We threw tubes, a fluke, small groubs and a Pop-R with nothing. We fished our way from the Shepherdsville ramp up to Floyd's Fork mouh and KOA and back down again. Guess the cold front Friday shut them down.
