All around the Lagoa (the lake between Ipanema and Corcovado) there are numerous little playing fields and areas dedicated to sports, including two skate parks. Every day, many teenagers come to these places to do their favorite sport, skateboarding. Skateboarding is a common sport in Rio, and different sorts of teenagers do it, from the rich kids from Leblon to the poorest kids from the favelas in the northern part of the city. In this photo, there are teenagers from both of ends of this class spectrum. In this park, they always skate together.
