I tried chumming with the chum your talking about last season,I also tried fish food,cornmeal,oats and corn.My results were not astounding,but hey,give it a whirl,it just didn't seem to draw the fish magically for me.I see other fishermen chumming their spots,but I also see them moving to new holes frequently.I do think that if you chum a spot with regularity over a long period,you could devolope a feeding zone for fish,but that's about the only way I think it would pan out for ya!consistantly.........j ust my feeble opinion!
