I'm heading out in a couple weeks for a 5 day trip around Lake Michigan, starting in Chicago, through WI, MN, MI, and IN. My route plan was going to entail hitting "avoid highways" on the GPS, and that was pretty much it! I've had good luck with that method so far, and generally I like to keep it pretty spontaneous, however this time I have the girlfriend with me, and she might not be as crazy about a 10 hour day on the bike as I am.
Any route suggestions, places to stay, eats, must sees, etc.?
