Jump in your sin wagons, but don’t get stranded at the drive-in. Martin County, which started a new drive-in movie series at its fairgrounds at the end of last year, returns this month with the nostalgic version of entertainment. For $5, quarantine crews can watch “Grease” on a 20-foot LED screen from the safety of their vehicles at 7:30 p.m. March 26. Arrive before showtime for food and beverage trucks and a classic car show starting at 5:30 p.m. Martin County kicked off its drive-in movie series with “A Christmas Story” Dec. 18 and “The Karate Kid” Jan. 29, but took a break in February during the Martin County Fair.
