Fished it again the 23rd. Tried the area a little deeper (54 fow) where the other anglers had done well as I watched on the previous trip. Nothing there on the scope. There was still lots of fisherman activity in that area. Went back to the spot I fished last trip. Some fish on the scope so set up to work them. Much slower than last trip. Had lots of fish come into the lure, would follow it up or down but not hit. Used different baits and lures over 5 hours for 4 fish. Water depth 39-40 feet. Best lure same 1/4 oz spoon as last trip. Ice still solid, clear and 5". Only a few other anglers.
