Maine Lobster Festival
Wednesday to Sunday. Harbor Park, Rockland. mainelobsterfestival.com
If your summer hasn’t been all it’s cracked up to be, claw your way to Rockland and join the crustacean nation known as the Maine Lobster Festival. Harbor Park and surrounding spots become not only the lobster capital of the world but home to a wide range of entertainment including the Sea Goddess Pageant, Coronation Parade, international lobster crate race, arts and craft show, cooking contests, Steins & Vines tasting event, live music and more. Don’t worry if you’re not a lobster eater, the festival also will have plenty of fried clams, shrimp, mussels and a slew of standard summer-fair food options. Here, it’s more than OK to be shellfish.

‘#Adulting’
7:30 p.m. Friday and Saturday, 5:30 p.m. Sunday. St. Lawrence Arts Center, 76 Congress St., Portland, $15, $7 for kids under 7. stlawrencearts.org
Vivid Motion Dance Company presents a humorous take on life set to one heck of a soundtrack. “#Adulting” opens with a high-school graduation and ventures into adult challenges, from paying bills to figuring out relationships and achieving some semblance of balance, while also delving into the purpose of life, the highs and lows of raising kids, and taking care of elderly parents. “#Adulting” features music by Queen, Enya, Cheap Trick, Avicii, Bobby Vee and Avril Lavigne, to name a few. P.S. If you’re on a budget, there’s a Thursday pay-what-you-can dress rehearsal performance at 7 p.m.

All attendees will receive a lantern, marker, wristband and commemorative drawstring bag.
