2007 was a good year for a few fish each trip, mainly walleye and white bass with an occasional striper when trolling. Had some good crappie action with minnows and tube jigs 18 inches below floats, not to mention a number of 5-7 lb. cats on the same rig. as you can imagine the crappies slowly take the jig down whereas the cats will take the float and the rod if not careful. Would really like to get out on Heidecke ice fishing, could be the best walleye fishing in all of Illinois. Hope the water level stays low so I can get my boat to the far side, under most conditions even a light breeze can make the bridge a dangerous, head crushing experience. getnany
