Charlie’s Drive-In, in Hortonville, Wisconsin

On a sleepy stretch of State Highway 15 in Hortonville, Wisconsin, sits a time capsule of kitschy car culture: Charlie’s Drive-In. Family owned since 1965 and currently operated by the brother-and-sister team of Rachel and Carl Mann, Charlie’s proudly dials back the clock and rocks around it for locals and road-trippers alike. “Every Tuesday is classic car night,” Carl tells us. “You come in with a vintage car, you get a free root beer with your sandwich.” And the locals do just that, lining up their Bel Airs and Packards to collect their perfectly chilled mugs of free root beer— made the old-fashioned way, with homemade syrup stirred by hand in a giant barrel.
