Don’t put the shorts away yet: There’s a ton of free stuff to do outside this weekend, including a county fair, a biking party, a clothing swap, and a concert for Chuck Brown.

Enjoy the fair weather
You’ll have to cough up some money to get into the much-ballyhooed Montgomery County Fair: But this is the D.C. area, after all, where there’s always a free version. The Arlington County Fair takes over the Thomas Jefferson Community and Fitness Center this weekend, offering live music, activities for kids (think games, puppets, bounce houses, face painting, and magicians), an Instagram-ready art installation, and lots of chances to watch piglets and goats race each other, oddly enough. Plenty of food vendors will have barbecue, ice cream, sandwiches, and more available for purchase.
Thomas Jefferson Community and Fitness Center, Friday, 2 p.m.-11 p.m.; Saturday, 10 a.m.-11 p.m.; Sunday, 11 a.m.-10 p.m.

Clean out your closet for a really fun reason
Ok, you caught us cheating. Technically the Summer Swap Shop isn’t free—if you count bringing all the clothes, shoes, and accessories you haven’t worn in years and have been meaning to clean out of your closet anyway. Lug all that stuff to Wunder Garten on Friday and receive a ticket for each item you hand over. You can use those tickets to snag stuff from other participants. Things in less-than-good condition will be recycled by DC Sustainable Fashion Collective, and minor alterations on items will be available.
Wunder Garten, Friday, 2 p.m.-6 p.m.

Find a new favorite biking path
Carb up, lather on the sunscreen, and WEAR A HELMET, FOR GOD’S SAKE, for the final Bike the District event, part of the city’s Year of the Anacostia. Gather at the Malcolm X Opportunity Center for a five-mile ride around the D.C. area’s less-traveled paths. Bring your own bike or borrow a LimeBike for free. Helmets are free for kids, and seriously, take them up on the offer. RSVP required.
Malcolm X Opportunity Center, Friday, 6:30 p.m.

See two takes on a queer icon
Bring the popcorn and blankets to the queer-women-owned distillery Republic Restoratives for the August edition of Queer Grrrl Movie Night, the monthly film series that specializes in stories told by and about queer women. This month’s showing is a double feature honoring trans activist and artist Marsha P. Washington, an instrumental figure in the Stonewall Riots. Catch screenings of the short film Happy Birthday, Marsha! starring Mya Taylor, the Film Independent Spirit Award-winning star of 2015’s Tangerine; and the 2012 documentary Pay It No Mind, (she used to say that’s what the “P” stood for) based on interviews conducted shortly before her death. Bring along snacks, but no outside alcohol (the distillery’s bar will be running). The movie starts at 8 p.m.
Republic Restoratives, Friday, 7 p.m.

Groove in Chuck Brown’s memory
Honor Chuck Brown’s birthday the way he would want: By enjoying some live go-go music. For the fourth-annual Chuck Brown Day celebration, the city is throwing a giant concert at the park named for the godfather of go-go. Crank Crusaders, Trouble Funk, and DJ Kool will be performing, as will—of course—the Chuck Brown Band. Lawn chairs and blankets welcome.
Chuck Brown Memorial Park, Saturday, 3 p.m.-7 p.m.
