If you want to cross over to the Iowa side of the river then take 52 up to Prairie Du Chien. Highway 20 is a frustrating ride on the weekends due to mega traffic with infrequent chances for safe passing. But, it gets you to the fun roads and is a fairly straight shot. If you take 20 watch for Elizabeth Scales Mound Road just west of Elizabeth and take it north. At the first stop sign (about 15 miles) turn left on Stagecoach trail and head into Galena. Or, if you aren't busy Sunday, hook up with myself and Motobeagle (and posse). We are going all over that Mississippi River area. Let me know if you are coming along or want more directions.
