to participate on the Carnivals and visit their relatives. Carnivals in Panama also feature large repurposed fuel trucks that are used for soaking attendees through the use of firehoses that are controlled and directed by one or more people that stand in a platform that is mounted on top of the truck. This is known as "culecos" or "los culecos". Trucks get their water from nearby, government-approved rivers, and the water is tested for cleanliness before use. Culecos are often performed from 10 AM to 3 PM, when the sun is at its brightest. Children and pregnant women are banned from participating in the culecos, and the trucks are always sponsored by a well-known Panamanian company or brand. The culecos are also often accompanied by reggaeton concerts. The open consumption of large amounts of cold, low-alcohol beer or Smirnoff, stored in ice-filled coolers, is common among attendees. Just like in Rio de Janeiro, some carnivals also feature floats, but they may have young women with elaborate costumes that stand as the "Queens" of "Calle Arriba" and "Calle Abajo", representing rich and working-class people, respectively. The queens are chosen through a contest and announced on October of the previous year, and are replaced every year. The queens are introduced on the first carnival day, and are always accompanied by a music band, who are present whenever the queens are present. Fireworks are launched on the last carnival night, to signal the end of the carnival. Peru Cajamarca The town of Cajamarca is considered the capital of Carnival in Peru. Local residents of all ages dance around the unsha, or , a tree adorned with ribbons, balloons, toys, fruits, bottles of liquor, and other prizes. At a certain point, the Mayordomo (governor of the feast) walks into the circle. The governor chooses a partner to go to the unsha, which they attempt to cut down by striking it three times with a machete. The machete is passed from couple to couple as each strikes the tree three times. When the unsha finally falls, the crowd rushes to grab the prizes. The person who successfully brings down the unsha becomes the following year's governor. Crime While generally peaceful, there have been issues with people using Carnival as a pretext for crime, particularly robbery or vandalism, especially in certain areas of Lima.
