National Automotive and Truck Museum
Auburn, Indiana
If you like to stare at old cars, and you like to stare at them in big, old, shadowy, echoey factory buildings, then you'll love the National Automotive and Truck Museum of the United States. We can't decide if the spartan exhibit spaces are a plus or minus, but they're definitely different.
The buildings belonged to the Auburn Automobile Company in the 1920s. Now they're packed with museum vehicles that range in age from an Autowagon (1908) to the 10 millionth GMC pickup truck (2009).
There's also a sub-museum of vintage toy cars and trucks, and a snazzy GM "Futurliner," a super-streamlined bus-of-tomorrow from 1953.
Behind the museum there is a row of restored vintage roadside bungalows, a diner, and a gas station.
