Chum found.
I picked up a 50 lb bag of Purina fish chow. Did a test run out to my local dock to see how it worked. Basically I soaked it in water overnight to get it broken up, "dusty" in the water, and sinking. Then, added more dry to the slop for a mixed bag of slowly sinking and floating. Threw some out...works like a charm. No idea if it will help catch fish yet but going out Sunday morning to try it. I've got some dry and a few bags presoaked and frozen. My plan is this. Find a fishy depth...test fish it. Hook one or tow...deploy chum bag. I figure one frozen block and one partially thawed block over the side in a mesh bag. Let it trickle down....slay the perch and maybe a few trout in the mix if luck smiles my way.
Pics to follow of the adventure on Sunday.
