More than 200 classic and antique cars roll into downtown for one of the biggest days on the Arlington calendar. Expect live music, local food vendors, a kids area, the Downtown Farmers Market, and Knapp Heritage Park open with shaded picnic spots. Stick around afterward and hop between downtown’s bars, breweries, and restaurants. With around 5,000 people expected, get there early for easy parking.

A full night of free music under the stars. The evening kicks off with the Levitt Youth Spotlight at 7:10, followed by Housequake, Texas’s premier Prince tribute band, at 7:30. Headliner Waterloo, a Dallas-based ABBA tribute band featured on Fox 4, takes the stage at 8:30 for two hours of Mamma Mia sing-alongs. Bring a blanket or lawn chair and grab dinner from the food trucks on site.

The Cousins Maine Lobster truck parks at Division Brewing for the day, pairing Maine lobster rolls, lobster tacos, lobster grilled cheese, and whoopie pies with local craft beer. It is cashless, so bring a card, and the CML app lets you order ahead to skip the line. An easy Sunday afternoon that tastes a lot better than your couch.

The club’s biannual sale is a treasure hunt in a parking lot. Shop slabs, cabochons, rough stone, jewelry, and lapidary tools, or bring your own finds and swap with fellow rockhounds. Whether you are a serious collector or just want something different for the grandkids, you will walk away with a story. Mark the calendar now, this one only happens twice a year.
