The decades seem to dissolve at places throughout the Midwest: diners with doo-wop on the jukebox, soda fountains with chrome fixtures, theaters that show two movies for less than $10.
We go to these retro spots for the charm. We go for the history. But mostly we go in search of a feeling we thought we'd lost. And we find it--in the sweet mingling of root beer and vanilla ice cream, in the sparkling smile of a waitress on roller skates, or in the silvery flicker of a movie in an open field on a hot summer night.
Click ahead for our picks of Midwest drive-in theaters, drive-in restaurants, soda fountains, diners and other spots where you can turn back the clock.

It's hard to say what makes a diner a diner. Some serve breakfast all day--some don't. Some make a great patty melt, others a great meat loaf and still others, a perfect coconut cream pie. Some play up their retro cred with oldies on the radio and album covers on the walls.
Others don't try at all. They just keep the neon sign working for 70 years and make the same chicken noodle soup as always, so regulars know exactly what to expect.
Every diner has its own personality, but what they share is a feeling. A sense when you walk in that the food will be good, hot and familiar; that the waitress will refill your coffee; and that no one will mind if you order a milk shake with your dinner. In fact, they might get upset if you don't.

Soda fountains have a language all their own. Egg cream (seltzer water, chocolate syrup, milk). Black Cow (root beer, chocolate syrup, vanilla ice cream). Green River (lime syrup, soda water). These are universals. But there are also semantic debates. Banana split (pineapple and strawberries, or butterscotch and chocolate?). Tin Roof Sundae (salted peanuts or toffee?).
As with any language, it's easier to learn with a native. Maybe that's why being taken to the soda fountain is a rite of passage. Maybe you recall twirling on a stool next to your mom and nursing a double-dip mint-chip. Or sinking spoons into mounds of marshmallow with your grandpa. Or sharing a malt with a boy from school.
Or perhaps the trip you remember best was the day the tables turned, when you brought your baby to the soda fountain and watched her spin on a stool and take her first lick from a mint-chip cone.

Before we all ate on the go, a meal in the car was a civilized affair at a place called the drive-in. It still can be. Try it.
At the drive-in, you park and consider the menu. (And that's important to do, because this is a local restaurant with such hometown favorites as pork cutlet, foamy root beer or fresh strawberry pie.) You chat with the carhop, or you tune in some good music. There's no rush. No burger on your knees or ketchup on your chin. No praying for a red light so you can find a napkin.
Yes, you're eating in your car, but you're not moving. A drive-through is a stop along the way. A drive-in is a destination.

Think back on the 1950s. Has there ever been an era we remembered so fondly, even if we were born a generation later (or even if we really know it wasn't quite so perfect)?
So go ahead. Put on those rose-colored glasses and join us in a little toast. Here's to poodle skirts, bobby socks and skinny ties. Here's to cruising in a Chevy with fins, windows down, the dial tuned to the Billboard countdown. Here's to first kisses in high school gymnasiums and teary breakups in the parking lot outside. Here's to the music that changed us all--and that our children and grandchildren still groove to a half-century later.
And here's to a few great Midwest places and events that, with good humor and a heaping dose of nostalgia, keep those memories alive.
