This weekend, the Fairgrounds hosts the 46th annual Back to the ’50s Weekend. Auto enthusiasts will have plenty to feel giddy about, as over 11,000 cars will line the festival grounds. There will be hot rods, muscle cars, and other classic vehicles from decades past. Check out new paint jobs, works in progress, and polished miracles on wheels. A swap meet will draw in those working on their own projects, there will be an artists’ market to explore, and live music on the Leinie stage will entertain all. There will also be plenty of food and drink vendors on hand. If you’re heading over on Saturday, be sure to take advantage of the park-and-ride offering. Find more info at msrabacktothe50s.com.
