Written Directions
Two lane, low congestion road through the country. Route 20 eastbound will take you all the way to downtown Chicago but west of Elgin is two-lane country road. Once in Marengo, go north on route 23 until it ends at route 14. Continue west through the town of Harvard (past the landmark fiberglass cow in the middle of town), the next small town being Bigfoot, which makes for some humorous photos. The Bigfoot cemetery and businesses plus there's a high school in the next town north bearing the same name. Continue west at Marengo instead of north, as an alternative destination out to Galena which is very scenic as well.
Scenery
Mostly country road which goes past a glider business in Hampshire and the Wild West Town (and railway museum) in Union. If you turn at the Wild West museum instead of heading into Marengo, you can continue parallel to route 23 on farm roads with less congestion but do head into Marengo if you need a quick bite or rest stop.
Drive Enjoyment
Well maintained roads all the way. A couple of sweeping curves as well.
Tourism Opportunities
Several businesses just west of Elgin but not much else until you hit the filling stations/truck stops in Hampshire. The towns of Marengo and Harvard have a little of everything. Walworth to the north also has a little of everything as well.
