During the month of June, there are several festivals and parties in Brazil known as the "Festas Juninas." They are especially popular in the Northeast, where people celebrate the birth of John the Baptist (São João) and the end of the corn harvest. During a festa junina, they play a style of music called forró, but there is also square-dancing where a leader calls out dance moves and the couples participating try to follow along. Foodwise, they typically serve corn pudding, corn cake, and pamonha (which looks sort of like a tamale and is also made of corn).
In the picture, Tawnya and I are standing in the cutouts for Lampião and Maria Bonita, famous folk heroes in the Northeast. Lampião became a type of Robin Hood for the region by stealing from the rich landowners, although I don't believe they did much to help the poor. Eventually one of the members of their group betrayed their whereabouts to the Sergipe state police and they were killed.
