I went to Sportmans Warehouse and picked up a chum can for $5 bucks yesterday. I was reading another thread and got the urge to give it a try. I loaded it up with herring,rice and tuna. Put it in the water and caught fish all day. Nothing big but I have never caught any fish in the area we were fishing in with any amount of consistency. It took the trout about 30 minutes to start showing up but after they got there they stayed tight to the can for about 4 hours. Give it a try it works.
