Has anyone here bought one of those artificial chum blocks that comes in a bucket? I was thinking of getting one, dropping it down a hole, fishing it a few days later to keep the baitfish, gills & crappies near by in a farm pond. Do they even work or a waste of $ ? I can see where it would take the fun out of finding the fish but I love to catch them & I let almost all of them go anyways. I guess it would be like baiting deer? I think I'm talking myself out of buying a chum block...
