Spent many years fishing the driftless area of WI around Dodgeville when I lived in IL. Once the initial rush to catch off as many of the stocked rainbows was over the fishing and the room to fish became fantastic. Fattest chub fed browns I've ever caught anywhere. Big, strong smallmouth bass in the streams I fished too. Remember catching 20" browns that would push 5#s. From caudal fin to tail was fatter than I've ever seen anywhere. When they say shaped like a football those fish were closer to it than any I've taken from a dozen other states.
