ALTAMONT — Do you enjoy making pirate sounds?  Do you say “Arrrrr,”  a lot?

If you do, matey, join the crowd at this year’s Altamont Fair where the Pirates of the Colombian Caribbean Aerial High Wire Thrill Show will give you plenty of chances to show off your pirate chops.

And, an opportunity to root (loudly)  for the good pirates as they cross swords  with the bad pirates high up in the rigging of the sailing ship that’s the stage set for one of the most unusual high-wire acts around, one that is making its Altamont Fair debut this year.

“Debut,” is that pirate? Maybe not.

Let’s say  “storming” the fair for the first time, creating a lot of mayhem, delivering thrills, and producing not a few laughs among the grandstand crowd of would-be pirates.

Meet the Murcia family: the aerialists, choreographers, swordsmen, set designers, and script-writers behind the half-hour show. There are, in total, six of them.

Outside of a certain film series that shall go unnamed, their show may be the best way to enjoy that pirate vibe of derring-do and ridiculous behavior (like a good pirate poking a bad one in the butt with a sword, as they walk, not the plank, but the high wire from mast to mast).

The Murcias  are Walter, who hails from Colombia and is the show’s co-producer with  his wife, Victoria, a Floridian who plays the mermaid in the show; their daughters Victoria, age 3,  who plans to be a mermaid very soon, and Elizabeth, the youngest, who is still considering her options. Rounding out the crew:  two teenage sons, Alexander and Antony, and one teenage nephew, Andres.

You couldn’t meet a nicer bunch of pirates.

Or nicer to interact with.  Audience  members are invited to take sides in the search for the treasure map. Mom Victoria has noticed the girls usually “go with the sons for some reason.”

If high-wire hijinks are not enough for you, the show throws in as well the Wheel of Destiny — two giant skulls rotating on a crossbones axis and whipping pirates around as they stand  inside and on the skulls, performing their usual skullduggery. Words cannot do it justice.

Dramatic lighting and music, cannons firing, and a mermaid complete the spectacle.

Walter and Victoria Murcia both come  from circus families that go back generations (their sons are the 10th generation). They met, of course, while performing in a circus.

But eight years ago, they decided to go independent, to develop their own show — “We wanted to create something different,” says Walter — and take it on the road.

Since then, their show and their growing family have played in countless cities and towns across America, as well as venues like the Los Angeles County Fair, a special engagement in Nagasaki, Japan, and in the Dominican Republic.

They began their eight months of touring in March, when Florida county fairs start, And they don’t stop until November, when they take their winter break.

On the road, the children are home-schooled.

Their website promises a final trick in their show that you “have to see to believe.”

We can say no more. We have taken the pirate oath.

We can say, however, that Pirates of the Colombian Caribbean will perform their 30-minute show daily at 2 p.m. and  8 p.m., with an extra show at 4 p.m. on Saturday. (Fair schedule can change, check the fair website.)

Eye-patches are encouraged, if you happen to have one.
