Expect to see three generations of fans at this Beatles extravaganza at the Oakdale Theatre. To provide full immersion in the sound, 20 bands will play a combination of indoor and outdoor stages, following carefully edited playlists to avoid duplicating tunes. A life-size yellow submarine makes a perfect Instagram backdrop.

It’s not too late to register your 1967 Mustang for this celebration of autos and the folks who love them. Or pile the family into the SUV and live vicariously at this gathering of more than 120 antique and classic cars, hot rods, and motorcycles. Be sure to save time for the exhibition of cars and memorabilia from the Indy 500.

Tie your kite tail fast and ride your bike to the Franklin Park golf course for this annual festival (originally slated for May 19, it fell victim to 2018’s erratic weather). If your gears feel a little sticky, pedal over to an onsite mechanic for a tuneup. Pack your panniers with a picnic, or indulge with lunch from a food truck. At Franklin Park from 11 a.m. to 4 p.m.

Scandinavian marauders return to New England as Mystic Seaport Museum inaugurates The Vikings Begin, an exhibition of early Viking weapons, shields, and other artifacts previously unseen outside Sweden.

The controversial Vinland Map, normally at Yale, is on display beyond the university for the first time in 50 years.

To make an informed vote in the People’s Choice competition for the best barbecue, you’ll want to buy samples from more than one of the “ribbers.” The music leans heavily toward rock; a separate stage offers karate demonstrations, dance performances, and more fun for children. A 25- or 50-mile bicycle ride on Saturday or a 5-mile road race on Sunday offer a chance to work off some calories.

For a real power trip, raft the Kennebec during a test of the river’s hydroelectric turbines. When the Harris Station Dam sends double the usual water downstream, the always-exhilarating ride on class 3 and 4 rapids becomes what guides call a “total rush” through the rock-walled Kennebec Gorge. This adventure for ages 14-plus occurs only four times per season.

Bluegrass meets the Green Mountains. National touring artists rave about the festival’s ardent fans and picture-postcard mountain valley setting. Fabulous sunsets are not the coda to the day.

Dust off your roller skates — or “rent” a pair (free) — and get ready to dance. The fifth annual celebration of Boston-born musical sensation Donna Summer is open to skaters of all ages and experience levels. In case of rain, leave all cakes at home. At City Hall Plaza from 6 to 10 p.m.

Start at the sanctuary garden at South Church to pick up a map and descriptions of the 10 other tucked-away stops on the tour. It’s a good chance to explore the narrow streets of the South End, Portsmouth’s first colonized neighborhood. You might find live music or cookies at some stops.

The Boston Art & Music Soul (BAMS) Festival at Playstead Field celebrates Afrocentric art, music, and culture. The musical lineup is chock-full of national headliners and emerging local talent on two stages — listen for vocalist Valerie Stephens, a Boston native, and The Woo Factor Band, a Berklee College of Music mini-reunion.

It’s not “James Beard serious,” say the organizers, but participating restaurants do engage in a little friendly competition for bragging rights. The ultimate winners are the diners, who can sample and compare variations on traditional clam chowder prepared by up to 10 Cape Cod chefs. Local bands provide the soundtrack.

Classes cover a range of yoga styles, from aerial to warrior, but those that promote restoration and relaxation are the most popular. “It’s about slowing down and tuning in to your body,” say event organizers. Most classes are appropriate for all skill levels. Live music, food trucks, and a vendor village with body products and yoga accessories add to the festive atmosphere.

Kids of all ages won’t want to miss Saturday’s Fireman’s Muster — a gathering of “big, old, and loud” fire equipment.

Other weekend activities include tastings of chili and chowder, an antique car show, and Maine-centric live music and crafts booths.

Readers never outgrow E. B. White’s classic tale Charlotte’s Web. All ages will be charmed by this adaptation performed daily by storyteller-musicians.

What began as a surf-shop party has grown into a community event with a grass-roots vibe. Bring your board if you want to skate the ramp.

This peaceful meadow with panoramic mountain views bore witness to a bloody clash between American and British forces in 1777. An encampment of about 150 reenactors conjures up the only Revolutionary War battle fought on Vermont soil. Tour one of the best-preserved early battlefields in the country and watch combatants face off on Sunday morning.

Psychologists say make-believe aids child development. So bring the kids to what organizers describe as a massive “multi-genre pop-culture convention.” Any character goes — some attendees switch among multiple ensembles. Along with hundreds of tabletop games, events include a costume contest, short skits, and a “death match” among characters from all genres (Superman vs. Mighty Mouse, Green Lantern vs. Red Ranger . . . ). The Kids’ Zone lets the small fry flex their imaginations.

The weekend kicks off when a fleet of eight windjammers sails past the Rockland Breakwater on Friday.

On Negro Election Day in 1741, African-Americans in Salem gathered to choose for the first time a representative to negotiate on their behalf in government affairs.

Bands play Motown and other old school music.

The sun has barely risen when tethered balloons lift off on Saturday and Sunday mornings. They carry passengers about 100 feet up for a liberating sense of floating on air. Not an early bird?

Break out your Hawaiian shirt for 5K and 10K road races and a luau.

Galilee is one of the largest, most productive commercial fishing ports on the East Coast, so it’s no surprise that this three-day celebration opens with the Seafood Festival.

Some vessels win prizes for best decoration; all leave with a blessing.

Having 435-square-mile Lake Champlain in your backyard is excuse enough for a party.

See how master folk artists craft hooked rugs, steel drums, Orthodox religious icons, or Mi’kmaq wooden flutes.

Whether radio programmers call it roots, Americana, or bluegrass, folk music never goes out of style. Artists know they’ve arrived when they’re booked to play Newport.

Fresh voices will also rise from the musical mix, including roots-gospel duo The War & Treaty, hard-driving twangy trio The Wood Brothers, and banjo-picking alt-rocker This Is the Kit.

Over half a century since it launched in the South End, one of the largest Puerto Rican festivals in the country draws tens of thousands of revelers for music, dancing, food, and plenty of family activities.

Sign up your kids — light-footed 9- to 17-year-olds dominate the competition. Pine Tree State musicians play on the Maine Stage all five days.

This celebration of Portuguese heritage promises a feast — and never disappoints. You might try a linguica or bacalhau sandwich, but most fairgoers prefer to cook skewers of beef cubes over a 40-foot-long barbecue. (Bring your own fruits and vegetables to add to the beef that is sold on-site.) Five stages feature music and folk dancing. For a break, sip a cappuccino and listen to soulful fado in the courtyard of the Museum of Madeiran Heritage.
